Hi All , only just found this great resource ( so at least I have the baxi to thank for that
)
Ok we have a baxi 105e and its been in the house at least 5 years ( worked fine all this time ) however its just become unreliable in delivering hot water .
From reading on here I checked the pushrod is working ok on the DHW pressure valve and the microswitch seems ok .
we`ve since sussed that hot water is delivered ok if the CH is off but if the CH is running its only luke warm to cold.
I`ve also noticed a loss in pressure recently and whilst my head was in there I saw a small water leak from just below the Diverter valve operating head ( this only drips when the CH is on ) it must have been doing it for some time as the circlip that holds the Diverter operating head on has little rust spots .
Questions :
1) Anyone any idea what the hot water fault is ?
2) is the tiny leak below the diverter valve enough to drop the pressure to zero or is that going to be the expansion thing I read about ?
3) anyone know what washer or O ring sits between the diverter valve and its operating head as Im reluctant to take this apart until I have the bits required to put it back together.
Any help/advice much appreciated
