Thanks Seco, sorry Ive not replied been away for two weeks at a hotel where the showers worked perfectly!! It is plumbed to the mains supply, and I thought about changing the selonoid so now that Im back I,ll send for one, if that don't work it looks like buying a new one! My missus insists that...

Hi Seco, yes the power neon is on but no water flow at all, Ive fitted a new on/off switch but the problem remains, the window that shows red for no water pressure and green for water pressure remains on red, be grateful for any views.

anybody any ideas please, went for a shower this morning and the thing wouldn't work, power supply on but registered as no water pressure, checked the header tank, that's fine, tried different settings but no luck. I think the on off switch may have stopped working, any help would be appreciated.

Had a close look again, which is difficult because its in a really awkward spot, and I think there is an adapter plate fitted, held on with four cross head screws, brass plate with what appears to be orange coloured gasket about 1/4 inch thick, when I had the boiler fitted about twenty years ago...

Thanks mystery man just had a look at the motor to see if I can work out whether its a later model as you described. It appears to be the later model, 2 cross head brass screws about 1inch long. If it is a later model would it be safe to remove the motor etc without causing a leak?

well thats a good start, just been talking to a man on the phone to see if they stocked the part and he said, 'be careful because the old Honeywell actuators (twenty years old or more) could not be taken off without draining down the system, if you tried to take it off water would pour out!! He...

Thanks for the advice brian1104 but I think dcawkwell hit the nail on the head and it is the actuater motor on the two port valve thats gone, Im presuming the boiler was in its hot water cycle when everything was switched off and then when it was all put on again the diodes failed leaving the...

Thanks again decawkwell, the lever certainly doesnt spring back, it doesnt even feel like theres any resistance so its obviously dead. If I can remember I can buy a new motor and change the old one over. Isolate electrics. take top off Honeywell 2 port valve, take out the two little screws...

Thanks again dcawkwell Ive checked evrything out that I can, thermostat, 5/2 programmer, my system has a two port valve and the slider feels very sloppy, it doesnt spring back as it should. Im not too sure what position the slider should be in, hooked in at the top or mid way any advice?

Thanks for the tip, looking at the controls to the boiler reminds me of a bowl of sphagetti! I, ll start with the thermostat and then try and work through it all, the 3 port valve has given problems in the past, the contractors burst a water main further down the road (they are doing every house...
