Out of the blue my Bosch Nexxt 3000 washer is now showing an E01 error code. The door shuts all the way and it sounds like it's trying to latch/lock but cannot. Is there anything I can do besides calling for service?
Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.

hope so, hubby wrote it down - WFMC2201UC/16. If that's not it, can you tell me where to find it on the machine? Thanks
you have a failed latch/lock assembly. it needs to be replaced, you can order this @ this will fix the issue.
Customer: replied 5 years ago.
does it require a special screwdriver to take out?
yes a torx screw driver, you can get a cheap set at lowes or a hardware store

and is it a simple swap the piece and all {should} magically work again :)?
thats what the tech sheets say, these do fail, there are microswitches in the latch that send a signal to the control that the door is shut and locked. if the board doesnt receive that signal it stops and give the code. hope this helps, thanks Bryan

Bryan, we replaced the part and the washer is still doing exactly the same thing, not latching. Is there something else we can try?

Relist: Other. trying to work on it now, The relay is clicking but it's not locking. Bosch 3000 Nexxt washer, Model WFMC2201UC/16, replaced the locking mechanism based on recommendation from previous expert.
Sorry , thats what the error code said, it has to be the main control module then, it didn't say that in the tech sheet though, thats all there is that can cause that. besides the latch.
Customer: replied 5 years ago.
Hi Bryan, since we are hearing a relay click on the main controller board, is there a chance that the replacement part is also a failure? Very unlikely, but who knows?

When switched should we hear a click on the locking mechanism? I hear the relay on the controller board clicking, but nothing in the latch mechanism.


If you hear the click comming from the control itself its the relay on the control not holding in to lock the door, I was going by the error code, they need to rethink these error codes and put all possibility on there, we can only go by the info they provide.

Eventually we do see the E01, but not right away.

Should I be hearing any clicking on the door lock mechanism itself when everything is working?

well it should lock, it has a wax motor it, you should hear it click locked

Customer: replied 5 years ago.
That is what is missing. How is that motor controlled? Is it an AC signal? Is it on the three wire connector on the lock mechanism?

it not the motor controller thats in the bottom and only controls the motor, the voltage to the lock mechanism is 120 volts ac, can you test for that?
Customer: replied 5 years ago.
Sure can, I'm assuming it is on the 3 wire connector? If not, where should I test?

well it has to be on and when the board is click test the latch, two of the wires will have 120 going to it, if the 120 flickers as the clicking begins them the relay on the board is bad


Customer: replied 5 years ago.
I'm not sure if my last message actually made it through. It was:

I can test. Is the signal on the 3 wire connector? If not, where should I look?

yes the three wire connector
Customer: replied 5 years ago.
Checking now, OK

I get about 30VAC between 1-2 and 30 VAC between 2-3 all the time. When I try to start a cycle, this does not change.

from 1-3 I get about 1.5 VAC and it might jump up to 2.5 VAC when the cycle tries to start.

Am I measuring correctly?
your reading it right, the board is bad. there needs to be 120 vac to lock the door.
Customer: replied 5 years ago.
Do you have a schematic of the control board? Do you have a suggestion for a replacement? (Are we talking big bucks?)
Customer: replied 5 years ago.
I see that. Sheesh. Can't blame you for that... Can you offer any other suggestions?

Thanks for your help.
