*** disclaimer - I'm not doing any work on my boiler myself, I have gas safe heating engineers doing it ***
Hello Forum,
I'm having problems with my Potterton boiler.
A heating engineer replaced the CH/HW motor on our simple CH+HW system, but afterwards the 3-way valve started making a lot of noise whenever the HW was turned on. Not sure whether the noise/vibration was just the inside of the valve mechanism sticking and then releasing rapidly, or a water hammer effect being caused in the pipes.
Unfortunately, after this started (but before the heating engineer returned to fixed the valve - I'm assuming some minor problem arising from the work on the motor beforehand) the boiler has started tripping out with overheat error about 5-6 minutes after firing up. This is not intermittent, it is every time.
The heating engineer has returned and replaced the flow thermostat but this hasn't solved the problem, so their boss is now going to come out and look at the boiler. The overheat occurs irrespective of whether it is CH, HW or both being turned on.
Any ideas on why my boiler might have started having overheat problems shortly after work on the CH motor was completed, but where the 3-port valve was making an awful clunking sound when moving? Could water hammer have damaged something physically in the boiler, or something else?
Thanks in advance,
J
