Philips 3300 Not Working? 5 Fixes (EP3347, LatteGo Problems)

When the Philips 3300 Stops Cooperating

A Philips 3300 that won't brew almost always tells you why with a warning light. The Philips manual for the 2300 and 3300 series has no numbered error codes. A steady alarm light means the drip tray, the grounds container or the service door. A flashing alarm light means the brew group. All warning lights flashing has its own reset: unplug the machine, then plug it back in.

This page follows Philips' North American manual for the 3300 series: the EP3321-EP3329 with the classic milk frother, and the EP3341-EP3349 with LatteGo. The type number is on the label inside the service door.

Quick Checks (2 Minutes)

• Water tank light: fill the tank, and push it in as far as it goes.
• Grounds container light: empty it with the machine on, and wait 5 seconds before sliding it back. Emptied with the machine off, the counter doesn't reset and the light stays on.
• Drink lights going on and off one by one: it's heating up or clearing air. Wait until they're all steady.
• New machine, watery coffee: brew 5 coffees first. The machine is adjusting itself.

Fix 1: Reseat the Brew Group, Drip Tray and Service Door (Works About 30% of the Time)

Alarm light on (steady):

• The grounds container or drip tray isn't in place. Push both fully home.
• The service door is open. Take out the water tank and close the door.

Alarm light flashing:

• The brew group isn't in place or isn't locked. Remove it and refit it.
• The brew group is blocked. Remove it, rinse it under the tap, lubricate it, and put it back.

To remove and refit the brew group:

1. Switch the machine off. Take out the water tank and open the service door.
2. Press the PUSH handle and pull the brew group out by its grip.
3. Before refitting, check that the arrow on the yellow cylinder lines up with the black arrow and N. If it doesn't, push the lever down until it touches the base.
4. Slide it in along the rails until it clicks. Don't press PUSH.
5. Close the door and refit the tank.

Brew group won't come out? Close the door, refit the tank, then switch the machine off and on and try again. Won't go back in? Close the door with the group out, switch off, unplug for 30 seconds, then switch on and refit it.

Fix 2: Clear the Clogs Philips Lists for No Coffee (Works About 25% of the Time)

Philips' "coffee does not come out or comes out slowly" row lists six causes, and "grinds but no coffee" adds a seventh:

• Pre-ground compartment clogged. This is also the cause when it grinds but no coffee appears. Switch off and remove the brew group. Push the handle of the measuring spoon up and down in the compartment until the coffee falls through, then clear it from under the group.
• AquaClean filter not prepared, or clogged. Take the filter out and try a coffee. If it works, the filter wasn't shaken and soaked before fitting. Replace it every 3 months.
• Grinder too fine. Turn the grind knob coarser (higher), one notch at a time, only while it's grinding.
• Brew group dirty. Rinse it (Fix 5).
• Coffee spout holes dirty. Clean them with a pipe cleaner or a needle.
• Limescale. Descale when the light asks (Fix 5).

Fix 3: All Warning Lights Flashing: the Reset (Works About 20% of the Time)

This is Philips' documented reset. "Reset the machine by unplugging it and plugging it back in." Before you switch it back on:

1. Remove the AquaClean filter from the water tank.
2. Refit the tank, and push it in as far as it goes.
3. Open the pre-ground compartment lid and check for clogged coffee. Clear it with the spoon handle, remove the brew group, and brush away the coffee that fell down. Refit the clean group.
4. Switch the machine on.

If that fixed it, the AquaClean filter wasn't prepared properly. Shake it and soak it before refitting. If the lights still flash, the machine may be overheated. Switch it off, wait 30 minutes, and switch it on again. If they still flash after that, contact Philips Consumer Care.

Air in the machine is a separate pattern: the alarm light on and the start light flashing. Fill the tank, put a cup under the classic milk frother, and press the flashing start/stop button. Expect small jets of hot water.

Time: 10-40 minutes

Fix 4: Fix LatteGo Frothing and Leaks (Works About 15% of the Time)

• Assemble it properly. Put the top of the milk container under the hook on the frame, then press the bottom until it clicks. Milk leaking from the bottom means it isn't clicked together.
• Clean it after every use. Rinse both parts under the tap, or put them in the dishwasher.
• Use cold milk. Philips tested semi-skimmed, full-fat and lactose-free cow's milk for good froth.
• Classic frother models: clean the frother, clear the small hole in the metal tube, and push the black plastic insert back into place with a blunt tool. Never froth for more than 90 seconds.

Fix 5: Descale, and Look After the Brew Group (Works About 10% of the Time)

Descaling (about 30 minutes) when the Calc/Clean light comes on:

1. Remove LatteGo. Empty the drip tray and grounds container, and take out the AquaClean filter.
2. Pour the whole bottle of Philips descaler into the tank, then add water to the Calc/Clean mark.
3. Put a 1.5 L container under the coffee spout and the hot water spout.
4. Hold Calc/Clean for 3 seconds, then press start/stop.
5. When the tank runs empty, rinse it, refill it to the mark and press start/stop again. The rinse takes 3 minutes.

Never use vinegar, or sulfuric, hydrochloric or sulfamic acid descalers. Philips says they can damage the water circuit, and that failing to descale voids the warranty. If the program is interrupted, rinse and refill the tank, then run half a tank of hot water and two pre-ground brews without coffee. Our Philips descaling guide has more.

Brew group care: rinse it weekly and let it air-dry. Clean it monthly with a Philips coffee oil remover tablet, and grease it every 2 months. A dirty or dry brew group also causes watery coffee and new noises.

Time: About 30 minutes
Cost: Philips descaler
Success Rate: About 10%

Coffee Not Hot Enough?

Philips gives three causes: the temperature setting, a cold cup and added milk. To raise the temperature, switch the machine off, hold the coffee quantity icon until its lights come on, and tap it to max (3 lights). Then press start/stop. Models with a temperature icon set it per drink. Preheat cups with hot water too.

When DIY Won't Work

If all the warning lights still flash after the reset and a 30-minute cool-down, contact Philips Consumer Care. The manual gives no numbered codes to decode on these machines. Contact details are in the warranty leaflet, and videos are at home.id/support. The manual's Restoring factory settings only resets the drink quantities. It isn't a fault reset.

Prevention

• Rinse the brew group weekly, clean it monthly, grease it every 2 months.
• Empty the grounds container with the machine on, and wait 5 seconds before refitting.
• Replace AquaClean every 3 months, shaken and soaked first.
• Descale when Calc/Clean lights up, with Philips descaler only.
• Rinse LatteGo after every use.

FAQ

How do I reset my Philips 3300?

For all warning lights flashing, unplug it and plug it back in. Before switching on, remove the AquaClean filter, push the tank fully in, and clear the pre-ground compartment. If the lights keep flashing, switch it off for 30 minutes. The Restoring factory settings option (hold espresso 3 seconds with the machine off) only resets drink quantities.

Why does my Philips 3300 grind but no coffee comes out?

Philips' answer is a clogged pre-ground coffee compartment. Switch off, remove the brew group, and push the spoon handle up and down in the compartment until the coffee falls through.

Why is the alarm light flashing on my Philips?

The brew group isn't locked in place, or it's blocked. Remove it, rinse it, lubricate it and slide it back until it clicks.

Can I use vinegar to descale the Philips 3300?

No. Philips says acetic acid (vinegar), sulfuric, hydrochloric and sulfamic acid descalers can damage the water circuit. Use Philips descaler.

Why does my Philips 3300 say to empty the grounds container when it's not full?

The counter wasn't reset last time. Always empty the container with the machine on, and wait about 5 seconds before putting it back.

Is there a Philips EP3320?

Not in Philips' 3300-series manual. The 3300 types are EP3321-EP3329 (classic milk frother) and EP3341-EP3349 (LatteGo).
