Got hot water coming out of the taps but not the shower head or hand help shower.Have stripped it all down to test each joint and restiction,all ok but as soon as it is all connected....same problem,annoying

You and the missus will have to share a bath in the kitchen sink. It will be just like in the 1970's ;)

Hi Ian is it a new install ? have you got enough head height (is tank higher than shower outlet) or is it a electric shower ?

It's a new install but working off a normal pump and pressure control.Will clean out the filter tomorrow as I think there may be some plastic burring still in the pipes from installation.

Hmmmmm good luck there,s always  summat in't there ! going wrong.
It doesnt have a check valve does it to stop back flow ? maybe wrong way round ? grasping at thoughts ,pressure switch ?  :-?

Episode 2.....

Couldn't find the filter....so
took off the heat exchanger and poured vinegar in,left for 3 - 4 hours and drained.Blew out some residue,gagged on the fumes for a moment or two and tightened everything up...so far so good.
Episode 3 will no doubt be along shortly.

Hi Nobrot,
Are you still with us?

Episode 3
Decided that there are more important things in life than a hot shower anyway.Back to the drawing board tomorrow....

Who needs a HOT shower, with this weather anyway?

THE BLOODY WIFE......................................

I had a similar problem, where I had tightened a pipe it had kinked but looked ok when dismantled.  When re-assembled and under pressure from the pump it twisted and restricted the water flow, stopping the boiler from igniting.  So after a week of trying everything you have tried, we just had to replace one 20cm piece of pipe and all has worked fine since.

Hi Tom,

Think someone else has mentioned that,will try tomorrow.

...and just give attention not to produce a bloody widow maker  8-)

Episode 4...Managed to sweet talk a guest into sorting it out,sort of.We dismantled all the end hoses and then blanked each one of separately to see if there was a restriction.That didn't seem to provide any answers nor cures,checked the diaphram,then decided to do that most heinius of crimes,read the instruction book.Absolutely clueless,so in a final act of desperation he pressed the reset button. BINGO.

To keep your lovely wife happy with HOT showers, and without further problems, maybe keep some spare batteries handy!!!!!

Episode 5.....Not so,back to cold showers I'm afraid.

Hi Nobrot,
From an old man, some technical advice, find someone who has a shower that works and use thiers.
Yours the plumbing Bulldog. ( Advice given on electrics also but this cost. )   

Have you got it working yet? If not;
I'm assuming water comes out of the shower from the
hot tap but the boiler isn't firing up - is this correct?

1. Have you cleaned the filter in the boiler?
2. If you run the shower and a hot tap at the same time does the boiler fires up and hot water comes out of the shower?
3. If 2 works then it sounds like the pump isn't producing enough pressure or there is a blockage in the boiler. Is there much difference in pressure (flow rate) between hot and cold water?
4. Try the shower tap 'upside down' - do you get hot water?
