Mr. Coffee Steam Espresso Maker Not Working? 6 Fixes (ECM160)

A Steam Machine Works Differently From a Pump Espresso Maker

The Mr. Coffee Steam Espresso/Cappuccino Maker (ECM160) has no pump. It heats water in a sealed reservoir, the pressure that builds there drives the water out, and one knob sends it to Brew or Steam. So when it won't brew or won't steam, the cause is usually the water you put in, the coffee in the portafilter, or a clogged frothing wand.

That design also explains two things owners run into. First, brewing and frothing share one fill of water, measured with the glass carafe. If you only fill for espresso, there's no water left to make steam. Second, the reservoir stays under pressure while the machine is on, so never unscrew the reservoir cap or remove the portafilter until you've released the pressure (Fix 6).

This page follows Mr. Coffee's own ECM160 user manual. If your Mr. Coffee espresso maker has a milk reservoir and push buttons, it's a pump machine instead: see our Café Barista guide.

Try This First

• Check the water line. Fill using the carafe's marks: the 2-cup or 4-cup mark for espresso, plus up to the steam line if you also want to froth milk.
• Check the plug and the On/Off indicator light. Mr. Coffee lists "appliance not turned on or plugged in" as a cause of both no coffee and no steam.
• Look at the portafilter handle. It should point straight at you when it's locked. If it's off to one side, it isn't locked, and coffee will leak round the edge.
• Feel the grounds. The manual asks for a fine grind, "like salt grains", lightly tamped. Packed hard, water can't get through.
• Frothing in the glass carafe? Mr. Coffee says not to. Use a stainless steel pitcher or a ceramic mug.

What's Going Wrong

Fix 1: Coffee Doesn't Come Out (Works About 30% of the Time)

Pressure can only push water through coffee that lets it pass. Mr. Coffee's troubleshooting table gives five causes: no water, no power, coffee ground too fine, too much coffee, or coffee tamped too hard.

Signs it's this one: the machine heats and hisses, but only a few drops reach the carafe, or none at all.

1. Turn the knob to Off and unplug the machine. Release the pressure before you open anything (Fix 6).
2. Check there's water in the reservoir. Refill it with the carafe: the 2-cup mark for 2 servings or the 4-cup mark for 4.
3. Empty the portafilter. Refill it only to the 2-cup or 4-cup line inside it.
4. Tamp gently with the back of the measuring scoop. Mr. Coffee warns that if it's "tamped too much, the water will not go through".
5. If it still won't pass, use a coarser grind. Mr. Coffee's manual gives two different grind instructions. It asks for a fine, salt-grain grind in "Before You Start", but its fix for this symptom is to "grind coffee to medium ground".
6. Screw the cap on tightly, lock the portafilter in, plug in, and turn the knob to Brew.

Time: 5 minutes, plus heating time
Cost: Free
Success Rate: About 30%
Difficulty: Easy

If this happened on a brand-new machine, run the manual's first-use rinse first. Fill to the 4-cup mark, lock the empty portafilter in, and run Brew until no more water comes out.

Fix 2: Coffee Leaks Around the Edge of the Portafilter (Works About 25% of the Time)

The portafilter seals against the brew head only when it's turned fully into the Lock position. Anything that stops it locking lets coffee escape round the edge. Mr. Coffee's notices warn that repeated bad locks can damage the seal.

Signs it's this one: coffee runs down the outside of the portafilter or drips onto the drip tray instead of the carafe.

1. Turn the knob to Off, unplug the machine, and release the pressure (Fix 6) before removing the portafilter.
2. Wipe the rim of the portafilter clean. Grounds left on the edge are a listed cause.
3. Don't overfill. Fill only to the 2-cup or 4-cup line.
4. Make sure the filter retainer clip is in the back position before you fit it. Don't press on the clip while turning: Mr. Coffee says it can break.
5. Insert the portafilter from the left and turn it to the right until the handle points straight at you. Mr. Coffee says this "may require force" at first. Don't push it past Lock.
6. Brew again.

Time: 5 minutes
Cost: Free
Success Rate: About 25%
Difficulty: Easy

Common mistake: leaving the portafilter in the brew head between uses. The manual says that can cause a bad lock, leaking and seal damage. Store it separately.

Leaking from the top? The manual also tells you to make sure the reservoir cap is tightened securely before switching on. The ECM160 manual has no leak row for other places. If water or steam escapes anywhere else with the cap tight and the portafilter locked, stop using it and call Mr. Coffee (see When DIY Won't Work).

Fix 3: No Steam From the Frothing Wand (Works About 20% of the Time)

The wand can only steam while there's water left to boil. Espresso uses the water first, so a reservoir filled only for espresso has nothing left for the milk. The other listed cause is a frothing wand clogged with dried milk.

Signs it's this one: the espresso brewed fine, but turning to Steam gives a weak hiss or nothing.

1. Turn the knob to Off, unplug, and release the pressure (Fix 6).
2. Add water for steam. Mr. Coffee's fix is to add 2 oz of water, or fill the carafe to the steam line and pour that into the reservoir. Tighten the cap.
3. Clean the frothing wand. Once it's cool, pull the black rubber piece off the bottom of the wand. Rinse it, wipe the wand with a damp cloth, and refit it.
4. Plug in, and turn the knob slowly to Steam. The manual says it takes a few seconds to heat before it starts bubbling.

Time: 5-10 minutes
Cost: Free
Success Rate: About 20%
Difficulty: Easy

To keep the wand clear, do what Mr. Coffee's clean-up steps say after every froth. Put the wand in a pitcher half full of water, steam it for about 30 seconds, then remove and rinse the rubber piece once it's cool.

Fix 4: Steam Works, but the Milk Won't Foam (Works About 10% of the Time)

If the steam runs out early or the milk starts warm, the foam never builds. Mr. Coffee's troubleshooting table names three causes: not enough water left for steaming, milk that isn't cold, and the type of milk.

1. Fill for both jobs. For 2 servings with milk, fill the carafe to the 2-cup mark, then to the steam line, and pour all of it in. For 4 servings, fill to the top of the metal band.
2. Use cold milk straight from the fridge, in a stainless steel pitcher or ceramic mug, filled about two thirds, so the foam has room. Use about 4 oz of milk per cup (8 oz for 2).
3. Start steaming once the coffee begins to brew. Submerge the wand, turn to Steam, and move the pitcher in a circle. Turn back to Brew before you take the pitcher away, so the coffee finishes.
4. Try a different milk. Mr. Coffee's advice varies across its own manual. The cappuccino pages recommend 2% milk and say whole milk makes finer bubbles. The troubleshooting table says to use 1% or skim "for best results".

Time: 5 minutes
Cost: Free
Success Rate: About 10%
Difficulty: Easy

Mr. Coffee calls frothing "a learned skill". As the milk turns to foam, the bubbles get very fine and the sound changes. The manual says those are the signs your milk is ready.

Fix 5: Espresso Runs Through Too Fast (Works About 10% of the Time)

Water takes the easy path through coffee that's too coarse or too thin a layer, so the shot rushes out pale and weak. Mr. Coffee's troubleshooting table gives exactly those two causes.

1. Use a finer grind, closer to the salt-grain texture the manual asks for. Mr. Coffee suggests a quality grinder or burr mill.
2. Fill the portafilter to the line for the number of servings you're brewing: the 2-cup line or the 4-cup line.
3. Tamp lightly, just enough to level the coffee.
4. Use the matching water mark on the carafe. Extra water just dilutes the espresso.

Time: 5 minutes
Cost: Free
Success Rate: About 10%
Difficulty: Easy

Fix 6: Release the Pressure Before Opening It (Works About 5% of the Time)

The reservoir holds hot water under pressure. Mr. Coffee warns that opening the cap or the portafilter while it's pressurized can scald you, repeats the warning on nearly every page of the manual, and gives one procedure for releasing the pressure first.

⚠️ Safety: Never force the reservoir cap or the portafilter while the machine is on or still hot. Steam and hot water can spray out.

1. Unplug the machine.
2. Put the carafe under the portafilter, and turn the knob to Brew.
3. Wait until no more steam or water comes out.
4. Now remove the reservoir cap.
5. Turn the knob back to Off.

Time: 2-5 minutes
Cost: Free
Success Rate: About 5%
Difficulty: Easy

Do this every time before you refill, empty grounds or take the portafilter off. After a cappuccino, Mr. Coffee's steps are to finish the brew, turn the knob to Off, unplug, and then release the pressure.

When DIY Won't Work

Stop using it and call Mr. Coffee if:

• Water or steam escapes from anywhere other than the portafilter spout or the frothing wand, with the cap tight and the portafilter locked
• It won't heat, or the On/Off indicator light stays off with power at the outlet
• The power cord or plug is damaged, or the machine has been dropped
• You smell burning, or the outlet's breaker trips

Mr. Coffee's manual says there are no user-serviceable parts inside and not to remove any service covers. Its 1-year limited warranty says that trying to repair or adjust any electrical or mechanical function voids it. For service, call 1-800-MR COFFEE (1-800-672-6333) in the US or 1-800-667-8623 in Canada. The model number is stamped on the metal plate on the bottom. Don't take the machine back to the store: Mr. Coffee says warranty repairs go through its own service centers.

The manual lists only one replacement part, the glass carafe, which you can find through mrcoffee.com or the same phone numbers.

Keep It Brewing

• Empty the reservoir after every use. Mr. Coffee says not to leave water in it between uses.
• Never fill the reservoir to the top. Use the carafe's marks.
• Release the pressure before opening the cap or portafilter (Fix 6).
• Steam water through the wand after milk, then rinse the rubber piece.
• Store the portafilter outside the brew head, and hand-wash it: it isn't dishwasher safe.
• Delime every 1-3 months, depending on use and how hard your water is:
  1. With the knob at Off, fill the reservoir to the top with undiluted white vinegar.
  2. Brew just until some vinegar comes out, then Steam until some comes out.
  3. Unplug and leave it overnight.
  4. Pour the vinegar out by turning the machine upside down over the sink.
  5. Rinse the reservoir twice, half full each time.
  6. Brew and steam with fresh water at least 4 times, or until you can't smell vinegar.

FAQ

Does the Mr. Coffee ECM160 have a pump?

No. It's a steam espresso maker: water heats in a sealed reservoir with a screw-on cap, and the pressure in that reservoir drives the brew and the frothing wand. That's why its fixes are about water level and pressure, not priming a pump.

Why does my Mr. Coffee espresso maker run out of steam?

There isn't enough water left. Brewing and frothing share one fill, and espresso uses the water first. Fill the carafe to the steam line as well as the espresso mark, or add 2 oz of water, as Mr. Coffee's table recommends.

Can I froth milk in the glass carafe?

No. Mr. Coffee says the glass carafe isn't suitable for frothing. Use a stainless steel frothing pitcher or a ceramic mug. The carafe's lid is designed to sit under the portafilter spout to catch the espresso.

How much coffee goes in the ECM160 portafilter?

Fill it to the line inside it: the 2-cup line for 2 servings or the 4-cup line for 4. Mr. Coffee warns that overfilling stops the portafilter locking properly, which can cause leaks and damage the seal.

Can I use descaler instead of vinegar?

Mr. Coffee's ECM160 manual only gives a vinegar method: fill the reservoir with undiluted white vinegar, brew and steam a little, leave it overnight, then rinse with at least 4 cycles of fresh water. It doesn't mention commercial descalers.
