i use a temperature prob. i measure the flow on the cyclinder and the rads. the rads had trv fitted. it is possible the trvs are fitted on the wrong side but this is unlikly

what different does that make

Hey everyone, Am working on a hideaway y plan system boiler, customer said that the hot water works and the radiators works upstairs but none of the rads work downstairs. At first I assumed it was the pump I discovered that the pump was working, I then assumed it was air lock so I turned off...

Well that true, but before I order any parts, I first make sure that all other parts are ok such as aps, flow switch and I always check the basics. I went to a boiler yesterday (28i). the customer said the hot water works fine, but the heating does not. This was a new fault coz I’ve never had...

TURNED OUT TO BE THE PCB, REPLACED IT ALL WORKING... THANKS EVERYONE FOR YOUR ADVICE

i have done my best, i have tested all the components that why i believe is the pcb. as i said i'll find out on monday. if am wrong i got the comments received on this site to help me, but am quite sure the pcb will work

am going back to the customer house with a new pcb --- i will let you know if i was right.....

no is not a broken neutral, don't u think i have though of that, the pcb send the pump neutral 240v, this neutral send the fan neutral 240v some way, unsure how exactly. it has to be the pcb,

as you know you have to wires going into the fun, when i attach my multimeter lead across the fan i get 0volt, when i attach my probe on live on fan and one on earth i get 240, and when i attach it on neutral on the fan and the other on earth i get 240v. the pcb supplys the fan power, it...

all the flow switch and pump switch and air pressure switch are working correctly, i have tested them on ohms. i got continuity when the switch was made and ol when not made. i believe the aps is not going in the open position, however when i tried to link the air pressure out or even take a...

Thanks for the reply, the reason I have suspected the pcb was because when I tested the fan with my multimeter on live to neutral I got 0volt, however when I tested it against live to earth I got 240v and when I tested it agains neutral to earth I got 240, I suspected I have a neutral fault...

true, but why does the air pressure switch not make, why is the pump reverse, it has to be the pcb

i was told by the manufacturers that the fan will always be 240v on both terminals

it does not have a ignition pcb, and the air pressure switch is fine, fan appears to be ok coz is not stuck

sorry yes the pump is starting and yes the flow switch are fine and making contact, i have tried and checked all components including thermisters and there appear ok
