I had A77 fault keep appearing on my Ariston microGenus HE32 boiler. (Condensate trap)
I narrowed the fault down to the recuperator at the top right of the boiler. I removed this and there was a metal residue build up on the floor of the recuperator housing that was partly blocking the right...
I have a Zanussi DSW909 Dishwasher that is blocked somewhere. I keep having to remove the clear tube at the rear and blow into it to reset the safety valve. The machine will then run for a few days and stop again when I have to reset the valve again.
It appears that the machine is blocked...
