Bosch Washer Er:01 and a Cycle That Will Not Start Because the Door Is Not Confirmed Shut

What Er:01 means

Press Start and nothing fills; the display reads Er:01 and the washer acts as though its door were open. On the Nexxt and Vision front-loaders Bosch defines this as the door switch not being actuated or the lock not engaging. You may also see it written E:01 on a WFMC3200, while the WFMC6400 and Vision machines print Er:01, so owners often search both versions.

Common causes of Er:01

Door left ajar or laundry pinched in the seal
Latch tongue on the door worn or cracked
Lock assembly that no longer engages

✓ One safe check you can try

1. Open the door all the way and look around the rubber seal for a sock or sleeve caught in it. 2. Wipe the latch tongue on the door with a dry cloth, removing lint and dried detergent. 3. Close the door with a firm push until you feel it catch. 4. Start a short cycle. If the error repeats and the latch looks cracked or bent, stop and call us.

! Why to stop there

Prying at the lock with tools can crack the plastic housing and cost more than the original problem.
A door switch and a lock look alike on the display, so replacing one without a test often means buying the wrong part.
Taping or forcing the door to hold it closed defeats the safety lock that stops the drum opening mid-cycle.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Er:01Er:01 questions

Why does my display say E:01 and not Er:01?

Some Bosch models, such as the WFMC3200, label the door problem E:01, while others, such as the WFMC6400, show Er:01. The meaning is the same.

Is a loose door catch covered by the warranty period?

It depends on your original coverage. Our own repair work carries a 30-day workmanship warranty on the part and labor we supply. Check your original terms for any manufacturer coverage.

Could a full load cause this?

Yes. Overfilling pushes clothing into the seal so the door can't seat. Lighten the load and see whether the lock catches before assuming the part has failed.
