Hotpoint Aquarius condenser dryer, TCM 580p. Where can I purchase a pump microswitch?

has to go in by back to remove drum

your pump may not be working then it beeps

check filter duct for fluff allso aluminium box at front in bottom make shure its clear of any fluff

my hotpoint condenser dryer ctd40 keeps cutting out when turned on ?

The secondary microswitch controlling the door is shorted. Check the microswitch which is located at the door perimeter and have it replaced.

I think that I have already suggested some possible reasons for the prob you are experiencing with your dryer, but I don't think I have mentioned the fact that the pump could be fauty, you should be able to hear it running, just a thought , you never know.

the steam gets condensed back to water and pumped away so sometimes draining problems cause poor drying. is the machine plumbed in according to handbook?
also your dryer filter may be blocked but this is not accesable without the dryer box being stripped down.

remove panel on rhs looking from back and you will see a chamber with a microswitch on top. either micrswitch is stuck, pump faulty or a lint blockage

I am not familiar with this particular unit, but I have a condensing dryer (Malber) which pumps out the water by itself. I am guessing that your unit requires you to empty a bin manually. Even if the bin is empty, I think the unit thinks it needs to be emptied and that is why the dryer will not work to give you hot air. If you do have such a bin, it might have a weight switch which the unit uses to detect if the bin needs emptying. See if the weight switch is working. The same weight switch idea is used on dehumidifiers.
