Tumble drier tripping breaker

Lorddrakul

My three year old tumble drier is tripping the breaker.

If I put it on a cold cycle, it works fine. The drum turns and the fan runs, but when I put it on even a low heat setting, it will run for 30s to 1m and then trip the breaker.

I looked it up and got a brand new, OEM heating element, complete with two sensors, and I chnaged it out. But, alas, no joy.

What am I missing?

Its a Bosch, domestic market model.

You don’t say if it is a vented or condenser , if it is vented remove the lid and where the 3 core mains lead enters the cabinet you should see a suppression coil, if it feel sticky disconnect it and try it again, ideally you need a meter to see where it is going to earth

Indeed, it is vented. Thanks for the response.

Right, will try that.

I have a multimeter, what am I looking for on the coil?

The Red Ace

The suppressor will have three leads , two connected across live and neutral and the third going to earth, if there is leakage to earth it will trip, disconnect the L and N leads and see if it trips. If the problem is not there it is the case of going through it with the meter to find where the fault lies.

Cheers for that.

As it only seems to happen on the heat cycle, hopefully the control stuff is ok.
