I will pay reasonable price for a used controls cover part Number 907706 I dont want a new one as the boiler will be replaced in 12-18mths Mods - is there a way to post this where the trade will see it?

Boiler working fine but need basic service. Any suggestions local CORGI person? Must have extensive Potterton Prima range Profile experience

Number 10 FD 8409 702391 Part way through last rinse cycle it tripped the MCB in my Consumer Unit. When latter was reset, it didn't trip out again. Display on washer is dead and none of the switches have any effect. Drained off water: no blockage and pump impeller rotates freely. Outlet...

A known fault with this boiler is to do with Air Pressure Sensing, either the switch itself, the associated flexible tubes, the restrictor, the venturi on the flue or the boiler cover sealing. Quite a lot to diagnose, never mind the otehr stuff - valves, sensing, electronics etc. As a...

I realise that old radiators will die eventually and I have replaced many of mine over the years. I believe the usual failure mode is a small black pinhole which leaks where the corrosion eventually breaks through. Has anyone any tips for inspecting rads to detect this kind of problem...

Leaving house unoccupied Dec-Jan> Boiler a bit iffy and gas costs a lot so I am planning to drain everything. But normal draining doesn't get everything out does it? Queries DHW: The loft tanks are grey asbestos type (1975 build). Will the water below the outlet crack the cistern if it...

My old boiler keeps on kettling even though I have used all the methods mentioned here. The resulting air finishes up in the highest rad so I bleed it off. I am puzzled how the same water circulating in the CH system can keep producing air after localised boiling (= kettling ?) has occurred...

Works Ok for a while then no heat. Elements OK. I see 3 sensors: 1 One inside the bottom outlet duct. Looks like an old fashioned power transistor - not user resettable 2 One near heater elements and seems to be wired across the heating elements: looks similar to 1 - not user...

Need to replace my 36x18 copper indirect cyl for the 3rd time in 36 yrs. Hard water plays havoc here even though I have my boiler temp cranked down to 65 (brrrr) and one of those electric magebtic coil thingies on the rising main. I see Screwfix have stainless versions: Sounds like a better...

Water level in F&E has increased since last inspection some months back. Suspect a very small/slow leak from DHW into Cyl heating coil. Both CW Cistern and F&E tanks are on the same platform in the loft but the CW cistern being bigger has a water level at least a foot higher, so any coil leak...

Need to extend my exisiting cable run to my PIR light mounted 3m agl on the outside house wall. 1 Do the Regs require the 1mm pvc Twin and Eth cable to go in conduit? 2 Even if they don't is it a good idea to stop uv degradation of the cable? 3 Is the black round conduit and fixings...

Saving up for condensing boiler. Meanwhile anybody scrapping a Potterton Prima 60e with this model of Electronic Boiler Control Unit in working order? If so I would be intereseted in buying at a reasonable cost to keep as spare.

My pump occasionally runs although all 3 actuators (2 zones + Hot water) are closed. Naturally its a bit noisy because its pumping against "blocked" pipes. I have checked the boiler overheat and overrun stats and they are not triggering. Boiler shuts down when actuators closed. I...

These pumps are said to be self -regulating as TRV's open and shut etc. However, they do require choosing one setting out of 3 first. How do they regulate themselves? - I guess it cannot be any vanes moving but must be the electronics sensing the flwo resisitance (= electrical load) and...

Inlet valve shuts on/off noisily several times during start of cycle. After filling, rest of programme runs fine. Checked filters on inlet tap connector and on machine - clear. Dismantled inlet valve and inspected solenoid etc - OK. Removed and cleaned the ribbed pipe going to the sump...
