Hotpoint ctd40 drier light flashing

[Lower]

Our tumble drier recently seems to have developed a fault.

Periodically the on off switch starts to flash and then all the other lights flash at the same time.

Drier continues to run.

Any ideas what might be at fault?

Hasn't done it for a while but its now started again.

Time delay and high heat light flash.

only seems to happen when we've used the tumble dryer in high heat.

Anyone? Any help much appreciated.

I did check and clean the condenser which was fairly fluffed up. Don't know if there would cause an error though.

Give me the numbers from top to bottom on the left. High heat is no1 I think.

Thanks for your replies rocks1.

Time delay is light 1

High heat is light 3

Clean the pump out at the back , loads of gunge in the pump causes this.

Will try that, thanks.

Its not done it since i cleaned out the condensor. Should i do the pump anyway?
