Hotpoint Wt741 - Door Error Following Capacitor Replacement
Hello,
I recently had the common issue with flashing LEDs. I purchased a replacement capacitor, followed someone's procedure for replacement and sure enough the flashing LED issue has gone.
However, when I went to run a cycle, I can hear the door mechanically lock but for whatever reason the LED for "door locked" doesn't illuminate and the cycle doesn't start. After a period of time a door error message comes up on the display.
Can I really have caused this by replacing the capacitor on the PCB, if so can I replace another component? What should I check for?
I cannot believe the door lock is broken as before the flashing led issue, it was working ok.
Any advice is very welcome.
Many thanks,
Alex

Hotpoint WT741 shows door error after capacitor replacement
- The problem
- After replacing a capacitor to cure the previous flashing LED fault, the machine mechanically locks the door but the 'door locked' LED does not light, the cycle will not start, and a door error is then displayed.
- Likely cause
- The accepted reply says the lock is probably engaging, but the switched power feed from the door lock is not reaching the rest of the machine. Possible causes mentioned were a faulty door lock, a disconnected or broken wire from the lock, or a fault within the main PCB. The PCB fault was suggested as the most likely of those possibilities, especially given the earlier flashing lights issue.
- What fixed it
- No confirmed repair was given. Recommended action was to check for anything obvious such as a disconnected or broken wire, but not to guess at component replacement. If nothing obvious is found, further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Door mechanically locks
- 'Door locked' LED does not illuminate
- Cycle does not start
- Door error appears after a short time
- Check for an obvious disconnected or broken wire from the door lock
- Consider possible fault in the main PCB
- Parts or tools mentioned
- Replacement capacitor
- Main PCB
- Door lock
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Replacing a capacitor shouldn't cause a problem unless by any chance it's the wrong one. If the door lock is locking then it's working, however, once locked it should pass power onto the rest of the machine and it appears this is where the problem lies. Either power is not being passed on (still possibly a fault on the door lock but rare) or the wire which takes this power onto the rest of the machine is disconnected or broken somewhere. The other possibility, and possibly the most likely (especially after the flashing lights) is that there is a problem inside the main pcb. I wouldn't guess at anything. If you can't see anything obvious get an engineer in. This article will help explain exactly how most door locks work which can help in diagnosing faults.
