PROBLEM RESOLVED Replaced PCB and the boiler is now functioning properly. It's probably the last thing you'd want to change ££££, but having checked that everything else was ok, it's a case of £120 for a new one, and hold yer breath it works! Only have to persuade the customer that...

Ran thru a load of checks with Vokera tech dept today. He believes it to be a fault in the PCB, based on the fact the pump is turning, the diverter is actuating but the fan/burner doesn't kick in. Will let you know if new PCB solves the problem.

UPDATE Removed pump head - everything looks fine. Impeller turning freely. Removed the diverter valve actuator. That's working okay. The exposed valve pin is moving freely manually. Automatic air vent on the pump can be heard venting upon system refill. Interestingly...

Thanks Martin, System is in Glasgow and pretty new. Never really seen any probs with scale, but it's worth a look at this stage! Cheers mate.

Thanks for your reply 45yeargasman, Will do. The notched head of the impellor is turning when I take the bleed screw out, but i will remove & check. A new build. There's no chance this is a one pipe system? Highly unlikley I'd think. Thank again mate.

Thanks for getting back. The 22mm return is not getting hot, but the flow is briefly for about 3" below the isolation valve, but when the burner cuts out it immediately goes cold again. Would this be a symptom of a stuck diverter valve? Display is showing the temperature. Green...

Really struggling. Any ideas lads?

Vokera Linea 28. approx 9 y/o installation in a new build. My problem is that I have hot water but no heating. I have been installing two bathrooms in a flat. In one bathroom the existing rad was replaced with a 'designer' rad, and in the other the existing rad was removed, and the pipes...

Cheers lads, thanks for your help.

Hi there, I have a Vokera 20 80 RS Flowmatic that was serviced about 6 moths ago. Sometimes the burner won't fire when I put a hot tap / shower on, but if I switch on the heating to 'constant' then switch it off immediately, the burner will fire up when I put hot tap / shower on. Any ideas...

So Nige, all Saniflo problems have ceased to exists, and no-one will be searching the forum for previous soloutions to their problem? There's always one....

Just had same problem with a Sanibest. Two hours with the fecker. I did eventually get it to hold. What I did was give the inside of the rubber tube coming out of the unit a smear with washing-up liquid, and pushed the joining spigot down as far as my strength would allow. You should hear a...

Haa, just checked receipt and it's actually JUST over two years old!!! Arghh. So do you think it's worth repairing, or chucking? Thanks, Gary

Hi, have problem with my Hoover VHD8412. Programme selector wasn't working so found the main PCB burned out. I then traced the wire on the PCB that seemed to be causing the problem, and found that it runs down to the connector block on the motor where it is badly burned out. My question is...

Hi repairing the drain hose is an easy job that most diyers should be able to manage. Just cut away the damaged part with a stanley blade, and join a new hose to the remaining old part with a hose connector like this...

Hi there, I have a Hoover 1400 AAA VHD8142 washing machine. I tried to put on a wash today, only to find that it is lightinging up like a Christmas tree whenever I turn the selector dial to any of the programs. That's EVERY light on the fascia on! I switched it off at the socket for a few mins...
