ariston micro mffi

[bobbo85]

Fault on ariston micro combi.It is ok on c/h but no h/w, no pump.no fan,nothing when the c/h is on h/w is coming through very lukewarm,flow switch im going back to fit,what do you think

Other than thermistor (changed a couple of these) theres not alot else..

What sort of flow switch is it?

Thanks rob,its a black round type at the back,right above the hot outlet pipe connection on the boiler.I went to get one today and (2) suppliers never had them,i got told they were £8.00 so i phoned ariston to check if they were looking for the right part and he said they were,but £8.00 for a flow switch,it looks like its a complete part you change,maybe you just change the insides
