No definitive answer ? I was called out to a 33HE tonight with the exact same problem.

I am looking for an alternate supplier of replacement cartridge for the shower mixer valve. It is approx 8 years old & dripping. Bathstore want £156.00 for a replacement! Any ideas?

May well just require new DHW thermistor but probably requires a new diaphragm in the diverter valve. Buy the genuine one as although expensive comes with all the fibre washers & seals. Can be a right pain with leaks so replace all the washers you remove!

Thanks for that Freddy I'll contact my local Building control next week.

I am in the process of purchasing a large end terraced house which has main road frontage to the gable end with door & windows on ground and upper floor. The side of the house is on a side street at right angles to the main road with a bricked up door but windows on this elevation. The other...

Probably by-passing at diverter valve. Do you have any more information on model of boiler?

You probably need to decide between an unvented cylinder and heat only/system boiler or a combi boiler. Either way you can lose the tanks.

Are you sure it's E4 and not EA or FA?

Does your boiler have an external roomstat? If so check it is calling for heat/ I would be inclined to bridge out the timer Ci-Cl the clocks do go a bit dicky sometimes. See if it stays on .

Is it a standard 24i RSF? Has the overheat stat tripped? Small red button sort of + shaped on top of case left hand side

You have 2 x 2port valves somewhere? Sounds like one may be stuck. Hope you have a by-pass on this system.

CH Thermistor

Is tap fully open? Have you tried backing the tap up? Reduce the flow- see if temp improves

If it sounds like a plane landing it usually means the heat exchanger has debris in it or is partially blocked This may be a piece of fibre washer dislodged when you changed the dv. Probably needs taking off and cleaning but you need RGI to do this. If you're lucky it may just be some air...

If the boiler is functioning correctly in Hw and CH you can probably rule out the diverter unless you have left a bit of fibre washer in the system and its stuck in the heat exchanger. Does it sound like a plane landing? Could alternatively be a host of other things like a noisy or failing...
