Potterton Suprima 30

[jbrett]

Hi All.

I have a Potterton Suprima 30 boiler in my house which was fitted from new about 3 1/2 years ago.

About a year ago the boiler developed a problem where it would start up then shutdown a few minutes later leaving the red light flashing. Initially I got it started again by pressing the Reset button, but at times I have had to power off the system totally and leave it for a short while. The problem reoccurs from time to time. The tell tale sign that the boiler has stopped is a noise coming from the airing cupboard (sounds like the pump).


When the boiler was serviced in February, the heating engineer said that I had the temperature on the boiler set to the maximum, and he duly reduced it to about 75% of maximum. This made no difference to the problem - if anything it possibly made it worse! I've increased it back upto maximum.

I have a relative who has had similar problems on the same type of boiler. He ended up paying about £260 to Potterton to fix it - PCB replaced.

While I have tended to live with the problem, I am about to let my house, so ideally need it fixed.

Any other instances or resolutions of this problem?



Thanks,

JB.

Does the boiler get a bit noisy before cutting out? If so it's pos the overheat stat tripping, pos due to poor circulation, pos due to defective pump or clogged pipework/heat exchanger.

It's quite likely your pcb needs attention, choices are (a) resoldering poor connections (b) Have the pcb reconditioned approx £50 (c) buy and fit new pcb which have been improved approx £140 or have some fit a new one.
This subject was a regular feature about 18 months ago, suggest you do a search for 'suprima' or look at my earlier posts starting march 2003.

As has been explained, there's a number of things which could be causing the problem so you really need an engineer to look at the boiler. Not that it's easy to find unpredictable faults.
