Stuck filter screen screw on DeLonghi BAR32

I've tried several times to remove the BAR32's boiler outlet filter for cleaning, but the screw doesn't move when I try to unscrew it (see Figure 28 in the user's manual).

Even clamping the screwdriver with a pair of vice-grips to create more unscrewing torque doesn't help.

How can I remove the outlet filter's screw?

I have ran hot vinegar water through, it sounds like it is laboring to "bring the water up" is the sound.. it takes a long time & it seems not enough pressure to force water through the coffee.

Could be several things.
  • In the bottom of the water tank is a spring loaded "valve" that may be stuck shut. It is much more common for it to be stuck open.
  • There is a filter in the suction line to the pump. There is a chance that the hot vinegar loosened something that is now plugging the filter.
  • The hot vinegar may have damaged the pump. Cold vinegar may have been a better cleaning fluid. (A cold citric acid solution seems to be popular too now days.)
  • If the relief valve was lifted (opened) during this procedure, it is possible that it is not seating tightly.

If this was my machine, I would replace the filter and pump because they are the most likely items to be a problem. It is not a hard job but one does have to be patient and careful. I would take a picture every time I removed something just to be sure I got it back together right.

I've included a link to a part supplier part diagram. You can see the pump and filter.

Good luck. DeLonghi EC155 Cappuccino Maker Parts

Screen Alert: General Alarm What does this mean

General alarm means the machine has detected a serious fault. There is a section in the instruction manual that may help. If not, read on.

Persistent "General Alarm"

This means many things. If the transmission is not stuck, check the main boiler has not burnt out (open circuit). This happens when the thermoblock labyrinth runs dry and overheats, a common problem caused by leaks, limescale, milk blockages or water filter contamination. Replacing the boiler is the only fix, a difficult and expensive process, experienced fixers (or nothing to lose) only.

If the transmission is getting stuck there may be obstructions, the lead screw may be worn or the limit switches could be faulty. If cleaning and grease on the screw/bearings don't help then replacement is a tricky job only for confident hands. Approach with caution.

I just got a eam 3500 machine. On first time instructions, no hot water would come out. produces a good cup of coffee though. When i've tried to froth milk for a latte, no milk is added to coffee. I have...

There is a blockage in the steam/ hot water circuit. By trying repeatedly to use these functions the steam boiler has now overheated and blown a thermal fuse ( thats why the alarm is displayed and now the infuser is in the wrong position for removal). If this machine is under warranty you should return it as soon as possible. If no warranty and you are a handy person (genuinely) then post again and i can help you fix it. No Good luck Rick.

My precious Gaggia Classic machine has developed a "fatal error". It will not pass water through the shower head. I have tried cleaning, re-priming to clear air block, several times over. The pump appears...

Remove the shower, then the 2 allen wrench screws for the diffuser, careful do not loose the spring ad valve seat that is above the diffuser, now turn machine on to see if water will come thru, if water flows, problem is either screen or diffuser blockage, if no water then you need a stronger descaler because blockage is in the boiler, at the solenoid or from the pump. Most likely in the boiler, if you have a boiler gasket go ahead and open the boiler to clear the blockage.

Replacing the pipe unit

Here's how it works....
An initial short run of the pump draws water from the reservoir into the boiler where it is heated by an electrical heating coil. There are two outputs from the boiler, one from the top runs through a pipe to a steam valve. When the steamer handle is turned, the steam valve opens and steam is piped out through the steam tube for frothing milk. The second output from the boiler is on the underside and is stopped by the normally closed flow valve. When the water in the boiler reaches the right temperature, a sensor switches on the OK light. When the light is on, the user pushes the pump switch and more water is pumped from the reservoir. The pressure in the boiler increases because the pump is trying to push in more water and this forces the spring loaded boiler flow valve to open allowing hot water to run out. As the sump filled with ground coffee is fitted to the boiler output, the water is forced through the coffee and out of the sump where it pours into a waiting cup.
When enough coffee has been poured, the user switches off the pump. The boiler pressure falls and the spring on the flow valve pushes the valve shut again.
------------ The first three steps aren't strictly necessary for disassembly however if you're using a long handle screwdriver then removing the base makes it easier to gain better access to some of the screws.
Step 1. Remove the screw on each base arm.
Step 2. ... then lift and remove the arms.
Step 3. Remove the two screws on the base of the unit. Unlike in this photo I would recommend you avoid resting the machine on its back unless you are sure it has been completely drained. The black plastic base can now be pulled away allowing easier access to some of the screws that will be removed later.
Step 4. Undo the two screws on the top rear.
Step 5. Remove the coffee tamper by pulling and twisting.
Step 6. Remove the three screws. These are anti tamper screws and are star shaped with a nipple in the middle.
Step 7. With these screws removed, the top may be lifted away. The hotplate on the top section is still connected by a couple of thin wires so lift it carefully.
Step 8. To help with shifting the top out of the way, disconnect the hot plate/boiler heater connection. This will allow you to push the top of the unit away giving you the room you need to get inside.
Step 9. Unscrew the electrical safety earth and move the earth wiring out of the way.
Step 10. Use some long nose pliers to pull out the circlip that holds the boiler inlet pipe in place. Pull out the pipe to disconnect it from the boiler once the circlip has been removed.Step 11. Unscrew, remove and clean the diffuser.
Step 12. Remove the two screws . The black plastic underside casing can now be pulled away (plastic tabs need to be pushed aside ). Step 13. Pulling away the plastic underside once screws and tabs are removed.
Step 14. Loosen the four black Torx (star shaped) boiler screws . Water in the boiler may leak out at this point so ensure the unit is upright and a towel is placed underneath.
Step 15. Remove the four nuts (three arrowed) from the underside of the boiler unit.
Step 16. Lift up the top of the boiler assembly along with the steam outlet and place to one side. The two halves of the boiler assembly are sealed with a rubber gasket which should remain attached to the upper housing. Make sure this is properly in place when reassembling.
Step 17. The lower boiler assembly can now be lifted out.

You need to reset it. Unplug machine, remove waste container and tray. Put the waste container back in without the tray and slide a knife under the waste container, close door. Plug in. It should reset. Turn off, replace tray and waste container and turn unit back on.

Easier, call their 800 number and they'll walk you thru it.

Could be scale build up. Do you have well water? You should run a descaler or white vinegar through the unit often to keep the boiler outlets clean.

Unless you are saying that the pump just doesn't run, ie, no noise, vibration, etc. Then, thanks for the warning that their pumps are bad.
