Hi, I have error E40 on Electolux EWG1440W washing machine and the door interlock switch is black so I guess I need to replace this. The bit that goes into the interlock switch is also black. Does anyone know what this part is called so that I can buy this part too?

Product no: 914511300

Serial number: 815 00150.

Thanks.

Electrolux EWG1440W E40 door lock fault query

The problem
Electrolux EWG1440W washing machine showing error E40. The owner suspected the door interlock because it appeared blackened, and also asked for the name of the matching part on the door that enters the interlock.
Likely cause
The accepted reply says E40 can indicate the door open circuit, door interlock, wiring, or main PCB. A faulty door interlock was described as the most likely cause, but this was not confirmed. The matching door part was identified by function as the door catch, and it would only normally need replacement if obviously broken.
What fixed it
Recommended action was to check the door catch rather than replace it solely because it is blackened. Replace the door interlock only if found faulty; the door catch should only be replaced if it is visibly damaged or broken. The exact repair was not confirmed in the thread.
Checks to try
  • Error code E40 reported
  • Door interlock reported as black
  • Part entering the interlock considered to be the door catch
  • Accepted reply noted E40 may relate to interlock, wiring, or main PCB
Parts or tools mentioned
  • door interlock
  • door catch

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Error E40 "Door open, Interlock, wiring, or main PCB", so although a faulty door interlock is the most likely it's not necessarily the fault.The part that fits inside the interlock shouldn't need replacing unless it is obviously broken, in which case the door interlock may be ok because the door catch's job is to fit inside the interlock and activate it.
