Odd Bosch Thermostat coupling
I am just replacing the heating element in our Bosch Classics washing machine WVF2042GB02. However I had to snip off the red thermostat wire before removing the heating element (attached picture shows wire in situ before snipping). I'm now not sure how to re-attach except by soldering it. The flat post the wire is wrapped round seems redundant as it's not connected to anything. All other thermostats for Bosch appear to have two wires and a plastic connector. Anyone encountered this and solved the problem?

Bosch WVF2042GB02 thermostat wire damaged during heater replacement
- The problem
- While replacing the heating element on a Bosch Classics WVF2042GB02 washing machine, the red thermostat wire was cut/snapped off and the owner was unsure how to reconnect it. The thermostat could only be removed once the heating element had been taken out.
- Likely cause
- The thermostat connection was damaged during heater removal. A forum reply suggested the thermostat should normally transfer from the old element to the new one, and that cutting it could be a problem if it was a thermocouple-type wire. An obsolete temperature regulator was also suggested as a possible replacement part, but this was not confirmed.
- What fixed it
- The owner exposed the broken point on the thermostat, cleaned it back, drilled a fine hole into the thermostat body, inserted about 3/4 inch of the stripped red wire, secured it with Araldite, then reassembled the machine. The wash then heated again. Exact temperature accuracy and long-term reliability were not confirmed.
- Checks to try
- Thermostat could not be removed until the heating unit was removed
- Machine was reassembled and tested on a hot wash
- Hot wash confirmed that heating returned
- Parts or tools mentioned
- Heating element
- Thermostat/temperature regulator
- Red thermostat wire
- Araldite
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Shouldn’t the stat pull out of the old element and fit into the new one? I can’t imagine it working if it’s been cut if it’s a thermocouple type wire.

I could not pull out thermostat until the heating unit was removed (as per your video!). If I've buggered it is it going to be possible to get hold of a new unit for this machine? I can't find anything compatible with WVF2402GB02...
It looks like it could be an obsolete part. Is it this? Bosch Neff Siemens Obsolete Regulator - Temperature

Could be Andy. As the wire had snapped off I reasoned that it would just have carried on into the thermostat. So I found the broken point on the thermostat, buffed it back and drilled a fine hole through, the drill seemed to break through into an open space so I shoved 3/4 inch of the bared red wire into the thermostat and araldited it in. Re-assebled machine , switched on and BINGO a hot wash! Hope this will last.
Is it working properly with the right temperature? I thought those thermocouple devices work by air expanding up the hollow wire?
