E04 Error on Bosch Front Load Washer- WFMC3200UC/01- How to clean and/or change the drain pump

I kept getting an E04 error code on my Bosch washer. This means that I have a drain or pump problem. First, I need to trouble shoot before deciding to buy a new pump or to call a repair man.
2. Make sure the machine is unplugged.
3. There is a access door on the bottom right side of the machine. It looks like a circle. Turn the circle and remove. Get Towels! If there is water in there, it will be coming out onto your floor.
4. Open the cap. It looks and works like a gas cap on a car.
5. Clean any debris that you find there. Then replace cap.
6. Reach up and squeeze the hose leading from the tub to the pump. There is a little ball inside that hose which is a safety device to keep debris from entering the pump. If that ball moves freely (not necessarily easily, but freely), there is probably no debris to clean out. But, you can always check by removing the hose clamp and looking (not easy at this point).
7. If you found debris in either place, once cleared, you should be fine. The smallest item can cause this error (a hair pin, wet receipt, hair ball, etc...).
8. Replace the access door on front right.
9. Plug in machine and try another load. If you continue to get E04 code, then your pump is probably bad.

2. Make sure the machine is unplugged.
3. Remove the access door on the bottom right side of the machine again.
4. Open the cap again.
5. Put your finger in the pump motor and try to spin it. It should move, but not easily. If it moves easy, your pump is probably bad.
6. You can order a new pump motor or the whole pump assembly. The new pump assembly comes with a hose to drain your pump. The original part does not have this feature. No worries, changing the pump is easy and fairly inexpensive ($80-100)


2. Make sure the machine is unplugged.
3. You will need to remove the front panel of the machine for the easiest access.
4. Prop the machine front up. There is a metal plate that is attached to the bottom of the machine by 2 screws. Remove both screws. Lower machine back to floor.
5. Remove the door. IT'S EASY. Open door. Remove 4 hinge screws from the door (not from the frame). Be prepared to catch the door once the screws are removed.
6. Remove the front of the rubber door gasket. There is a thin round shaped wire that sits in the groove of the rubber gasket. There is a spring on the bottom of the wire, making it expandable. Gently pull the wire from the groove and set aside.
7. Remove the rubber seal from the front panel (frame of the hole) by unclipping the rubber from plastic notches around the perimeter of the hole. DO NOT Remove the rubber seal from the inside of the machine. Leave it attached.
8. Take the control panel off of the top of the machine. There are 4 screws (2 on each side). Remove the screws, gently pull out and up. No need to unplug the electrical panel. Place the panel on top of the machine.
9. There are 2 screws holding the front panel on. Remove both screws. (1 on each side, on top)
10. There are plastic clips on the inside of the panel. These work similarly to a bedrail attached to a headboard. Gently lift the entire front panel, unlatching it from the clips, then pull forward.
11. Get Towels! If there is water in there, it will be coming out onto your floor.
12. There will be 3 hoses on the pump assembly. Remove the hose clamps.
13. Reach back and unplug the pump. (Squeeze the plug at the pump motor and pull).
14. There are little rubber feet which attach the pump assembly to the bottom of the washer. Push the entire assembly back and lift up. (similar to the bedrail/headboard scenario mentioned above)

1. Reverse the above instructions.
2. Put rubber feet in bottom and pull forward.
3. Plug in pump.
4. Attach hoses.
5. Put front panel back on and pull down to snap into clips. Put screws in.
6. Put rubber gasket back on. Put gasket on notches. Put wire ring into groove.
7. Put the control panel back on. 4 screws.
8. Prop front of machine up. Reattach bottom to plate using the 2 screws.
9. Replace door, using 4 screws. This will take 2 pairs of hands.
10. Plug the machine in and try it out.
That is all. I am not a professional. I am single mom who has to do stuff like this on my own. Since the pump did not come with instructions and Bosch refuses to tell a person how to take the washing machine apart, I tired to find instructions online, but was unsuccessful. That is why I decided to share. I wrote these instructions from memory. Hopefully, I did not miss any steps. But it really is easy. I was unable to attach pictures, so I hope my descriptions were clear enough.

What is error code e04 bosch front loader washer

The "E04" error code on your Bosch washer refers to a drainage problem as you may or may not already know. ( it can mean door lock error, but that is usually a by-product of it not draining )

What you may have is either a partially clogged pump, or a faulty pump...the later being the least likely
