I have a 2.5kw Creda 79351 that looks to have recently burnt out its neutral wire at the 13A wall switch, the fuse looked to be ok.
I'm presuming it's an overheating issue of some sort and that the thermostat is at fault but wanted to confirm.
The thermal fuselink is intact. The resistance on...
Plumber here.
Discovered another valve in most awkward place, hidden behind cladding next to boiler.! Its not a complete unit as in the motor is a different make to the valve.
Anyway, the valve was leaking onto the motor and that is obviously the cause of the RCD trip.
Seems the...
Went to bed last night and left the HW switched to on. About 3am it tripped the RCD.
This morning - reset RCD put HW and CH on and RCD tripped almost instantly.
Reset RCD, HW only on, trips RCD after about a minute.
With HW only on, boiler did fire but seemed to clicked more times...
Definitely only found 1 valve (in the airing cupboard), unless there's another hidden elsewhere in the house (behind cladding etc).
Switch on boiler is set to 'fully pumped' and not 'gravity'. As is the programmer.
HW/CH both been on a good while now (hours) and no RCD tripping. Could the...
Fully pumped system yes.
Today I checked the wiring connections in the programmer. They looked all good but just tightened them up just in case.
Has the CH/HW on together today and both working fine, not had a trip out yet.
CH still does not work on its own though, so thinking the...
Valve is definitely 4043 so I guess 2 port.
I also thought the pump maybe causing the trip. Pump is Potterton Celsia.
Boiler is Potterton Profile 60.
Programmer has 2 x timers for CH and/or HW.
Currently been on HW only for nearly an hour now and no tripping.
Tripping only...
The valve is a 4043h. I've checked everywhere and all wires, pipes and joins etc appear dry, safe and good.
The fact that the CH doesn't come on at all without the HW on at the same time is making me a bit suspicious.
At the moment I'm trying it with just the HW on only with no CH and so...
Hi,
I have a fairly old potterton boiler, hot water tank, typical GCH and HW system. Digital thermostat and modern digi timer etc.
Recently its started to trip the electrics at the RCD. With the fused switch to the HW/CH off the electrics are absolutely fine with no tripping. Which is why...
Timer is a Horstmann (see pic).
The economy 7 set-up is in an annexe building that will be sublet on a casual basis. I want to stop tenants having the unrestricted immersion on all the time. With the timer they'll only be able to boost it for up to 1 hour at a time.
Pic of the meter also...
I bought an Economy 7 timer for my immersion heater.
Currently there are 2 x switches on the wall. One labelled restricted supply (eco7) and the other labelled unrestricted supply.
Both have a red and black wire going in at the top plus a brown and blue wire going in the bottom.
Now, I...
