any suggestions lost me

[ROB28]

its a worcester 24i combi gas boiler HW works fine but CH playing up can run HW all the time no problem but when switch CH on it comes on fine but after approx 20 mins it just goes off completely including HW if you then leave it for about 30 mins and run HW tap it works fine but no CH the CH is on an click out auto timer at 15 min intervals if you set that to come on and go off 30mins later and do that at 1 hr intervals right throughout the day and night it will come on and off and back on again no problem its like its overheating and just needs time to cool down someone suggested it might be the thermocouple and someone suggested it could be th pcb not sure myself can anyone help its giving me an headache lol

Why dont you just throw the combi out and fit a conventional boiler and storage cylinder.
These forums are littered with the problems that combinations boilers are nortorious for.
Not to mention paying expensive engineers to fix them.
My trusty oil boiler has not been serviced since I purchased it 7 years ago and its still going strong.

It's obviously an overheat fault. The dhw doesn't employ the pump.

So,

system could be sludged up

pump could be faulty/sludged up

CH sensor could be faulty

Maximum gas rate could be set wrongly

OH sensor will probably also want changing.

Whats the annual average cost of servicing a combination boiler and fixing their many faults.
Must run into thousands.
The UK would be better off if all the natural gas had been supplied to power stations instead of spending billions on natural gas supplies to every household . They could have built smaller local power stations with the billions saved on the domestic natural gas distribution network and people could have heated their homes with cheap electric heaters using cheap electricity.
When a gas shortage comes , the domestic supply is going to be switched off any way and at some time in the future it may be turned off permanetly making the gas grid useless.
What a waste. If only we had leaders with foresight.

It would also have given cheaper energy prices to people outside the gas grid and have left them less at the mercy of the oil suppliers.

Oh how I agree, modern gas turbine generator sets are so efficient that local generation is likely to be very very much more econonical, far less transmission losses and local hot water schemes could have been installed instead of gas piping.

If the leaders had foresight they would be wanted for real jobs.

i hardly think a combi costs thousands to run every year. my last one certainly didnt. people who insist on keeping their old 80's boiler with no energy saving controls and permanent pilots are wasting gas, and people who are heating an entire cylinder full of hot water each and every day to only wash the dishes and have one bath are the ones partly responsible for the inevitable forthcoming shortage of gas.

in my opinion you get what you pay for. buy a cheapo b+q combi and you will always have trouble. buy a qaulity appliance and you will have less trouble.

if you dont get it serviced properly it will also be more likely to be faulty on a more regular basis.

get a good one and keep it serviced and you will save yourself money and possibly help the environment.

what we also need are more housing schemes where they have a central boiler to provide for a number of houses or streets at a time. there are a few such schemes around here and ive heard they have been a great success

Sounds like the time delay for the Central heating is up the spout on the board.

I have had this fault on this boiler before and a new PCB solved the problem
