Dear Friends
Please, please, please could somebody point me in the right direction? Moved into this house (house is approx 10 years old) in September. Fully sealed system, HE Tribune cylinder, S Plan, drayton actuator on the heating side, honeywell valve on water side, grundfos red pump next to cylinder. The water is on timed and the heating on constant - drayton RTS2 thermstat in hall
(as elderly father has a health condition and needs a warm enviroment).
The grundfos pump would not switch off and ran constantly for nearly 48 hours (no call for heat from thermostat and kept firing the boiler up too - radiators cols). Called British Gas out and they replaced the Drayton actuator (and a new brass spindle section on the water pipe too) on 31 October.
All ran fine and we also had a new Vaillant boiler installed on 21 November (straight swap keeping existing controls). all good. But then on Friday 7 December, AGAIN the grundfos pump ran and ran and ran until I switched it off at the main fuse spur. British Gas came out and replaced the Drayton actuator again.
Sunday 9 December - same issue again - pump constantly running - called BG again who came out checked both valves using their multimeter, checked the junction box in the airing cupboard, the thermostat and the programmer wires - cant find the fault. All working fine - BUT AGAIN woke up this morning to the pump constantly running again. I switched the heating off at the myson programmer, but the pump still ran. Switched the boiler off at the fuse spur and the pump stopped - switched the mains on again 10 mins later and the pump is STILL running. BG been out again - 4th time for the same issue and again unable to find what is wrong. All is running fine again - the BG job is still open and the engineer will be coming back on Thursday 11 December. So, this intermittent fault was present with the old boiler and again with the new boiler. Almost feel like asking BG to contribute towards the new boiler, as had we known that this fault would still be here we wouldnt have had a new boiler fitted. The boiler is in the kitchen, so no frost stat issue. Please help, Im almost sucidal now !!! Could it be a faulty progammer? There is some live feed somewhere that is making the pump stay on and not swtich off when the room stat is satisfed. The BG engineer also checked for sticky microswtiches in both valves this morning.
Any suggestions would be greatly welcome, so I am armed with info when BG arrive on Thursday!! Thanking everybody in advance. PS Im un Huddersfield, if any engineers can diagnose and repair the fault - happy to pay!
