Potterton Lynx electronic not firing up

guyp1 · 25 Mar 2005

Was having a lovely hot shower this morning, turned off taps. The missus went in a few minutes later and complained of no hot water went to check boiler and find that neither CH or HW working all of a sudden. No lights although can hear faint whirring when I switch on taps or switch CH to constant bot boiler not firing up. I have only recently had a new diverter valve fitted maybe 4 weeks ago and all has been fine until today. Any help much appreciated. I know The Potterton Lynx electronic is old but we are moving soon and I could really do without having to replace boiler as new owners will probably be stripping out and fitting new kitchen anyway.

Hi

Ive got the same problem. I have a Potterton Lynx Electronic. I havent had any work done to it since i moved into the flat 1.5 yrs ago. Yesterday out of the blue the boiler just didnt work. Was totally fine the day before. No lights or ignition. I can hear the boiler whirring very quietly when i switch CH on - but no lights or ignition. Checked the fuse in a lamp and its fine...any other solutions? Ive recently been bleeding a radiator that sits directly next to the boiler. It took about 2 weeks with the valve open on the rad, for any water to finally come out of the radiator valve. It still hisses when i release the valve and air is still coming out. Would this have had any effect on the boiler? Please help!!!!

most probably one of the pcbs has gone check for water leaks as they are very often the cause of the printed circuit board going

I've often found that applying electricity is often the cause of a lynx board going tits up.

Check the transformer if there are no lights atall but you are getting power to your pump the low voltage side of the transformer may be fooked...

Hmmm could also be the thriving business of reconditioned lynx boards. Surely the worst electronics ever.

LYNX mk 1...what a boiler!

LYNX mk 2. What a piece of camels dung.

Diverters are a nightmare.

The fact that potterton improved with the puma is a testament to how bad the lynx 2 was.

At least potty puma's have the wax capsule, even if you cant ever get on one connection to replace the whole diverter if required.

I always thought the Lynx I was a pretty good design. Just a few leaks!

The LynxII was an even better design with a good PCB.

They took a backward step with the Puma though!

I have taken delivery of a Potty Envoy for disection. That will be an interesting example of how NOT to design a boiler. Does anyone know how to remove the HE assembly easily ?
