thanks for replies. have disconnected mains supply feeding the shower and let mains water water run into bath for a few minutes. a fair amount of grot came out! anyway, seems to done the trick

I have tried with shower head off. I've tried with shower hose disconnected, running for 5 minutes on cold Does anybody recognise a possible component problem? There was a bit of grot in the inlet filter before I cleaned it out.

Yes I have checked inlet valves fully open and as I said cleaned the inlet filter

have installed a Redring Expressions 500 six months ago. more recently have had problems with water getting too hot. even when the flow contol valve is fully open-maximum flow-the overheat neon lights up presumably because the thermal cut-out has operated. appreciate that input temp is higher at...

having problems with a washing machine, a Tricity Bendix Eco 5. It starts a programme with two or three short bursts of spin?? then the manually set programmer moves on to end of cycle in a very short time, about 25+secs. obviously, main motor and belt ok, and i have checked water-level...

having problems with a washing machine, a Tricity Bendix Eco 5.machine starts a cycle with two or three, short bursts of spin, i think, then the manual set programmer rapidly turns (about 25 secs) to end of cycle.main motor obviously works and have checked water-level tubes. suggestions welcome.

if your diagram is correct, where is the expansion taken up when three port valve is on heating only?

glow-worm micron. haven`t seen boiler yet, but owner has mentioned, "cracking noises". boiler is working apparently.i`ve come across similar situations with a few other types of boiler in the past and the owners have had their fans replaced by other operatives.apart from ignition spark shorting...

can anyone recommend a reasonably priced, and reliable, Flue Gas Analyser?

another suspect would be the gate valve that shuts off the cold supply to bathroom. older gate valves can stay closed because the spindle has broken, but this is not obvious as the wheel-head can still turn. does the wheel-head turn and turn in an anti clockwise direction? otherwise, try...

why has it only been working fine for "months"? have you drained it in the past? if you have not touched any gate valves, ie - closed and opened them, then suspect crud from bottom of cistern is partially blocking cold pipes to taps.

white wire passes through rubber grommet and connects to spark electrode. leave that in place, but disconnect from PCB when that is finally removed.when you have disconnected all other leads, small-nosed pliers may be helpful unclipping board from retaining lugs.

how`s about you show us in detail precisely how you managed to get these kwh figures in the first place.

i think Big All may be pointing in the right direction regarding estimates. how did you work out these figures? the dates don`t all correspond to quarterly billing. are you by any chance a master chef? do you use gas for cooking? recovery time for a 140 litre cylinder, not allowing for heat...

are the neons flashing? have you refilled the system? next thing to look at is the air pressure switch and tubes.

what nos. is your ideal icos? is it a15,18 or what? what are the approximate width and height of your cylinder? 900mm tall by 450 wide, should be the 120litre mark. if you are running the shower for a total of 10mins at a rate of 12litres a min. then as mr Agile suggested, you are using up...

AS A TEMPORARY MEASURE - AFTER ALL- IT MAY ONLY NEED A NEW O-RING, YOU COULD TRY SOME LSX JOINTING COMPOUND ON THE ORIGINAL O-RING. YOU WILL NEED TO DRAIN THE BOILER, AFTER ISOLATING THE ELECTRICS, BY TURNING OFF THE HEATING FLOW AND RETURN VALVES. THE DRAIN POINT IS IS JUST TO THE LEFT OF...

if you`r certain you have the pump flowing in the correct direction, then the cold feed from the F&E cistern, usually a 15mm pipe, should tee into the flow pipe( from the boiler)-on the suction side of the pump. within 6ins of this, the vent pipe (usually 22mm) should tee in, beyond the...

what model vokera is it?

IF "ALL OTHER RADS ARE ROASTING" THEN BALANCING WOULD SEEM A GOOD IDEA AS WELL AS TRYING 3)
