Mend Potterton Heating Water Heats Central

potterton suprima 30 not heating water?

my boiler heats my central heating but doesnt heat the water enough to wash pots let alone have a bath. Sometimes the pilot lights up and other times it doesn't. The green line comes on and the red light flashes which i believe means it is hot enough but i don't have any hot water. My central heating isn't on at the moment. It also has a seperate timer. The boiler is only five years old, any suggestions would be gratefully received

Make sure your cylinder stat is set high enough .
Usually 60.

With just the hot water on at the programmer, increase the stat setting on the cylinder. Do you know what the pump is? If you do, you should hear it kick in when you turn up the stat. It's usually sighted near the cylinder.

If you can't hear or feel the pump running, you could have a faulty stat or loose wire in the stat or 10 way box. (Electrics) Your 3 port valve may also be seized in ch only position or the actuator (motor) on top may have failed? 3 port valve next to cylinder too.

Unless you know how to test it, recommend you contact a local CORGI bloke.

Does'nt sound like a boiler fault. Probably a circulation fault. Maybe diverter valve or blocked pipework at the cylinder.
If it was the boiler the heating would'nt work.
