Hello,
I have a Bosch WFF 1401 machine, must be at least 8 years old but lightly used.
It has started to trip the electric when it's going through the wash cycle. However it works fine on the rinse and spin cycles.
Any ideas what could be wrong with it?
I'm trying to work out whether it's worth getting it fixed or buying a new one.
Many thanks in advance.
Paul

Bosch WFF 1401 trips electrics during wash cycle only
- The problem
- A Bosch WFF 1401 washing machine, around 8 years old and lightly used, was reported to trip the household electrics as soon as the wash programme starts after filling. Rinse and spin cycles worked normally. The door was also noted to stay locked until the power was switched off.
- Likely cause
- The most strongly supported diagnosis was a faulty heating element, because the fault occurred at the point the wash cycle would normally begin heating. However, the accepted reply stated that many different insulation faults can also trip the electrics, so the heater was not conclusively proven.
- What fixed it
- The accepted advice was that this type of fault often needs tracing with a specialist insulation test meter. A crude check by disconnecting the heater was discussed as a possible indicator only, but it was specifically noted as not being foolproof. The exact repair was not confirmed in the thread.
- Checks to try
- Machine fills then trips when the wash programme starts
- Rinse and spin cycles operate normally
- Door only opens once power is switched off
- Heater disconnection was discussed as a rough test only
- Parts or tools mentioned
- heating element
- insulation test meter
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

It could be the heating element Paul, especially if it only trips where you say, but tripping the electrics can be caused by dozens of different things, most needing a special insulation test meter to trace.

If it's properly insulated and kept away from moving parts it's a crude but potentially effective method but not foolproof. If the short was on the neutral return wiring for example then disconnecting the heater would take it out of the circuit and stop it tripping but it wouldn't be because the heater was faulty. Chances are though that if you disconnected the heater and it stopped it is most likely because of the heater.
