SOURCE: Vaillant boiler - heating OK, but no hot water.

Most likey problem is the diverter valve, not energising fully. This in turn will not move the little plastic lever arm that actuates the microswitch on the side, sending the signal to ignite.

You can buy a diaghram kit from most local plumb centres, you need to replace the diaghram and seals, don't forget the silicon grease to ensure the plunger doesnt stick. Kits less than a tenner.

You should have noticed before it stopped working completely the water had reduced in temperature before the weeks it failed.

To make sure it is a diverter valve fault, depress the microswitch if you can, when the hot water is flowing and hey presto the demand for hot water light should shine.

SOURCE: Drayton Digistat SCR thermostat not working.

Go online to www.cheapboilers.com who deal with this type of boiler. It would be very difficult to troubleshoot this boiler with the information supplied. I hope this will be of some help to you.
Sincerely, Shastalaker7
They should also be able to get you a manual for your thermostat.

SOURCE: New grundig pump is now making a kind of clicking

I was ready to pass your question and go to the next person because you said it was making a clicking, and I could not relate or diagnose that type of sound for that kind of pump. Thank God I decided to read to the end where you said rattling sound. that is what you should have said in the beginning.
1st, did you replace the pump cartridge or the whole pump unit? 2nd, is the pump in a different oriented position than the original pump position? The inner cartridge floats inside the pump as it rotates and if it is in an oriented position that allows it to bounce (to & frow) it will make this rattle sound; not serious but can be annoying. It is was a replacement cartridge, perhaps the new gasket and the old gasket are in place, thus allowing too much space for the cartridge and it therfore moves too much and rattles. Or, if it was replaced as a whole new unit. there is a problem with it that you should not be responsible for, except for the positioning orientation. Finally, if there is still too much air in the system, the air bubbles will jossle the cartridge untill you get rid (bleed ou ) the remaining air. Goodluck<Macgivor

The gurgling sound sounds like you have gotten air into the system. Try purging the air out at the bleeder valves. Also check and make sure that your water inlet is working.

There should be a pressure drain to purge out all the air. Sound like there is an air bubble in the system somewhere.

Radiators not getting up to temperature


depending on the piping configuration; Series loop or mono-flow, you might need bleed the system. If its a mono-flow you would have bleeders on the radiators. Bleed them only till you you have water coming from the bleeders. If its a series loop, you need to bleed them from the area of the circulator by the boiler. There is a urge system you need to use and see if you can get the information on how to do that. I would think that somene here as written a tip on how to purge a series loop hydronic system. Also check to see that you have somewhere in the 12-15 PSI on your system pressure.

That clicking and knocking noise you hear is called cavitation. It's when the bubbles of steam are cooled down rapidly and implode upon themselves. Cavitation is not a good thing to have in a boiler as it can cause dramas. This cavitation is more than likely because the boiler is firing too hot. A service technician should be called to turn the regulator down a little bit.
