theres a small diverter just up from the gas valve try bridging the microswitch if it then fires for dhw the diaphragm or valve as failed you can get these bits cheap from abkot

agree with gas man check micro switch as the man said ,do it your self or run hot tap and pay close attention to diverter pin

hi mark checked it out its the instant done a test on hot water themister as 2nd light along flashing says dhw sensor done ohms test only reading 3.52 ohms so would guess its that if not all change the diaphram

 

[Billy Bob Bob]

yes i agree go with the thermister first

 

[sparra1100]

yes i agree go with the thermister first

what should they be 10,000 to 13,000 ohms

11k cold the reading you got(3.52)was that a cold reading?

 

[desrob]

normal reading when hot...?as gas man is suggesting

 

[sparra1100]

boiler was on but there wasnt any hot water so cold in effect as no hot water for few hours so would have thought would have been around 7 or 8 warm but wasnt any warm last one i changed was on a heatline and that was this low and it was that

 

[sparra1100]

hi mark changed the dhw senser made no diffrence light was still flashing so pushed the micro switch on the small divertor and pulled on the pin got hot water straight away and the light stoped flashing so got to be that i would think only thing i was thinking could it be the micro switch or will it defo be the diaphram

cheers mate

you can either change the cheapo diaphragm sparra or get the dhw diff here DV 561 Baxi Instant 105E 80E Performa 28i 248728
as they have a tendency for the plastic innards to snap causing the same fault

 

[sparra1100]

yep al get the diaphram first as going away next week so dont wana get to involved and you must be able to buy the plastic inner if need be al ask at heat spares when i go today cheers mate
