very intermittent problem now for months

Boiler is a proteron suprema 50 (and yes I have changed the PCB )

So… the boiler fires up as it should from the timer the pump comes on at the same time and runs fine…. Runs for a while till hot then both turn off as they should and this on off cycle will run fine for a while no problem.

Then randomly the pump will not come on with the boiler.
Which causes the boiler to boil the water and then I get banging pipes. (the boiler running cycle will normally finish just as the banging starts)

Then the next cycle will start and the pump will come on with the boiler no problem as if nothing ever happened and run as it should for a fair while then maybe another random cycle where the pump will not come on with the boiler.

What do you think?
( This problem has slowly got worse over 3 months at first it would be once every week maybe.. now its every day)

Is the next stage to change the pump? (Even though it will work fine for long periods)

Or is this more electrical that the pump is not always being told to turn on

Any help would be great
Karl :dunno:

If you know how to use a multimeter and use it safely, then you need to check whether there is 240VAC at the pump terminals when the pump is not running, or test at the pump terminals on the boiler.

I am NOT a plumber or heating engineer, but I have found pumps either run or they don't (Some times get blocked, but that's for another time) I would suspect its not being told to run, If you have changed the pcb can you have a closer look and follow the pump connections and see if any of them have a "dry joint" I am thinking its hot inside a boiler and maybe the pcb is flexing?

thanks for the reply's guys I will check this over the weekend.

The morning heating is set to come on at 5am and for 3 days at 5:25 am the banging starts. (always after the heating has been on for 25 to 30 mins ,
once the pump has not come on for a few cycles and pipes have been banging, it then seems to carry on running fine till 7 when the heating goes off

this is the same in the evening when the heating comes on at half 5 by 6 then banging starts for a few cycles, then will run all evening

You haven’t said what system you have, but assuming you have a feed and expansion tank in the loft, check the water level is above the outlet pipe and that it is not pumping over when on, which could cause air to be sucked in after a short while stopping the pump pumping due to an air lock forming.

Outside chance, but simple to check.
