Hi . it sounds like the cold is stopping either due to an airlock or pump failure on the cold side. Your hot is continuing to come but is locking out on an overheat stat.
Are your hot and colds from a tank?
Hi there. Hot water is from a Megaflop. Cold, Im assuming, is from the mains. We have not water tank in the flat
Megaflow I mean
Sorry , just reread , yours is non pumped unit , but do you have a separate shower pump , pumping up to this unit?
You say its non pumped , then you say the pump whirs. Can you please clarify , thanks
I don't believe so, no - when the bathroom was installed there was no conversation about buying a pump
Sorry, the shower unit whirrs
Ok . is it running off a tank?
The hot is - from a megaflow.
Ok , and the cold is from the mains?
I believe so, yes, as we have no cold water tank
Ok . definitely a problem with the digital unit. I would be very surprised if both filters blocked up fully like that , normally it would be a gradual decrease in pressure. The control board sounds like it has developed a fault and is not allowing the solenoid water valve to open
How old is thew shower?
Its not too old , but it has definitely developed a fault . do you think you will repair it yourself?
No. My plumbing knowledge is zilch
Ok , you might find it cheaper in thelong term to replace like for like. This would only take 40 mins as the pipework wouldnt need changing or the wiring
Well, its only two pipes going in, one out , on pushfit fitting and rewiring is pretty simple,
Brilliant - many thanks for your help
