SOURCE: Shower diverter problem

It is very possible that a piece of rubber from the old washer or some debris has found its way into the shower diverter or the showerhead. The first thing to try, is to take off the showerhead and see if you get water without it. If you get water then your problem is solved!!! Puchase a new showerhead or take apart the old one and soak it in CLR or Lime-Away to clean it. If that doesn't do the trick than, Turn off your water supply to hot and cold. Remove the diverter (if possible) and inspect for debris. If you want you can also take out the hot and cold stems for a total inspection of the inside of the faucet. You can then flush out the inside of the faucet cavity with a Turkey Baster or something to that effect. Put it all back together ( use a bit of vasaline on all the rubber washers so they do not get stressed when re-installing) and you should be able to take a shower.....Also, if it was a cartridge you replaced, you may have inserted it 180 degrees opposite......Hope this helps.....Joe

SOURCE: re: combi boiler.

if you have hot water at the taps but the heating isn't working make sure the thermostat is set high enough for the boiler to run check the time clock settings are on.
if these are working it could be a faulty diverter valve switch not sending a signal to the boiler to run.

Sludge / furring possible in primary part but not if the ch & flow through hot tap are ok More likely it's the diverter valve. The rubber diaphragm inside is perished / holed. Replace

No hot water coming from combi boiler ( vailliant)


I have a BAXI combi Instant 105 HE bolier. It has been very cold for the past week and the hot water is not working (though the heating is). I have cleared the overflow flu pipe of ice but this has not solved the problem. Any suggestions?

Radiator heats up when running a shower.


Your boiler is overdue for a service.

Combi boilers are unlike regular boilers in that they have quite a few moving parts, it's vital that these are serviced annually if you want the boiler to remain reliable and to avoid expensive failures.

In your case, the diverter valve has most likely failed. Normally, when the heating is on this senses when there's a demand for hot water and temporarily diverts the primary hot water circuit to feed the domestic hot water heat exchanger. When the demand for hot water ceases the primary hot water circuit is diverted back to the central heating heat exchanger. The valve has a number of moving parts including a rubber diaphragm which can wear out and split and moving shafts which can seize.

When the valve fails it can leak and also can divert hot water to the central heating heat exchanger when hot water is used. The reason that only the highest radiators in the system are affected is probably because the failed valve does not necessarily cause the central heating pump to activate and circulate the hot water throughout the system (it does on some boilers though). If hot water is introduced into a cold heating system it will rise via convection to the highest points in the system like an old fashioned gravity circulation system which was unpumped.

Call a heating engineer out as soon as possible; I'm not going to advise how to do the repair yourself as gas appliances MUST be serviced by qualified persons only for reasons of safety. If you're lucky then the valve simply needs cleaning up and a few new diaphragms plus other minor seals and rings. If it's gone too far then the valve and possibly the manifold it's attached to will need to be replaced.

In the UK the part alone typically costs between £100 to £200 depending on whether it's just the valve or the manifold as well. The diaphragm kit typically costs up to around £15 and is routinely fitted when the boiler is annually serviced, and a new valve will already have new diaphragms fitted. For a routine service expect to pay for up to two hours labour (many can be done in one hour), but if the valve/manifold have failed it will be longer as one failure often causes other parts to need further inspection/repair.

I hope that I've helped you today, if so please return the favour by rating my answer.

Combi cutting out and overheating


is this a baxi 105? chances are you diaphragm has gone on your diverter valve. Or your diverter valve.
Do you will initially get a liitle hot water if your heating is on?

Our Baxi combi 130 HE heats the water OK but will not heat radiators. This has happened after a period of not using the radiators (ie. over the summer)


check the pressure it should be in  the green band, check the pump, inside the boiler cabinet lower right.
