Re: Bosch condensing tumble dryer (WTL55) condensation alarm

Belay that last message. It looks as though I’d not properly positioned the sump pump, and it wasn’t working properly. Ho Hum.

Seems okay now (although I’ve just about destroyed the plastic clamp that holds it in place)

Well, I knew it was too good to be true. Three days later, the condensation alarm is going again – the impeller is clear and the tube is clear, and the float seems to be operating correctly, so I’m mystified.

Just to close this out, with thanks!

And that was it. The impeller on the sump pump was bunged up. Took a bit of getting out and back (the cover was a bit fiddly), but it’s now absolutely fine.

Thanks again for your help

Many thanks for those suggestions, and the explanation of the process will be a great help.

I’ll take a look later today.

I did notice when I turned it on this morning that the water pump ran for a while and almost filled the water tank within a couple of minutes. After that it went ahead and dried with no problems or alarms.
