No Hot Water from Ideal RS Series Boiler

[jasta]

Hi, I have a Stelrad Ideal Wlx RS Series boiler (unfortunately I do not know the exact model). This boiler is quite old but extremely reliable until now. When the heating is set to come on the system provides hot water. If the system is set to just Hot Water (as required through the summer) then there is nothing more than lukewarm water.
We have had both the thermocouple and gas valve replaced last year for other reasons if this helps.

Probably a motorised valve in your airing cupboard faulty. If you do a search on this forum of motorised valves, 2port and 3port you will be an expert on them in around 30mins.

agreed likely a mv or tap stat faulty

Sorry also forgot to mention the boiler does not fire up when the water is set to come on although it fires up fine for CH ?

Sorry doitall - didn't see your reply til now. Cylinder stat and motirsed valve mean nothing to me I'm afraid. Think primary school pupil - then lower your sights (maybe not so bad really). Willing to try anything that doesn't involve tampering with gas supply.

Strangely following your replies (and having searched for the 2 port motorised valve) I noticed the stat on the cylinder and gave it a tap - and hey presto - I have hot water. Thanks guys - Big Help and much appreciated.
