Bosch WVD24520GB washer dryer won’t fully finish wash cycles The machine fills and drains smoothly. Nothing was found in the pump, and no Error messages on the display. On Spin or Drain programs it works properly, and it goes right through to -0- minutes, beeps, and releases the door...

Hi again, Q1: Is the thermistor mentioned below (Potterton Performa 28i - system was "humming" at 4am) the same thing as the "thermostatic sensor" of my Baxi Solo 3 PF? Q2: And is it also the same thing as its "integral frost-stat"?

Thanks Eric (and/or Mark) - very helpful! You wrote: "I have an old boiler ..." - well I do too, and she's always feeling the cold! :wink: I have seen something similar to that thermostat/timer at B&Q, and will have a look for wireless cylinder stats. Q3: Is there a wireless system...

Many thanks Dave, and to all who have responded! :)

Hi all, I saw from this thread in Nov 2004 that Part L building regs at that time require both room stat and cylinder stat: //www.diynot.com/forums/viewtopic.php?t=16134 Our situation has an old Thorn boiler which continues running reliably, but the only temperature control is the...

Yes, Dave, you might well be right. The boiler is downstairs in the kitchen (the controls and cylinder are upstairs in a cupboard off my office). The thermostat sensor fitted to the boiler flow pipe shows a resistance of about 1.3 M-Ohm at room temp, falling to below 1.0 M-Ohm as it warmed...

Thanks Gaz, I have had other boilers (esp Potterton) needing PCBs replaced, but before we put the total blame on the PCB on this one, how can I first check and eliminate the frost stat? Where is it anyway?

I drew down some hot water from the cylinder, and can confirm that the MV moves to all three positions correectly and as expected by the controller and the two stats. The pump runs continuously no matter which position the MV moves to, and does not even pause momentarily when the actuator...

Hi Dave, Thanks for your thoughts! Yes, it runs 24/7, no matter what the controller or thermostats are telling it. It doesn't seem to stop when switching from HW to both to CH or back, however, just now as I write this, the HW On is calling but the MV remains in the CH position, so I think...

Hi all, Here goes my first post on DIYnot – what a brilliant website – thanks to all its contributors! Our CH/HW system has been in and running reliably for about 8 years – Baxi Solo 3 PF, Siebe Lifestyle LP241 programmer, Drayton MA1 mid-position valve, Grundfoss Selectric pump, Drayton...
