anyone worked on many heatline products before...

[mutley racers]

I have the below instantaneous water heater which is showing an f5 fault. I cannot find installation instructions for it any where and client doesn't have. So called glowworm who say they cannot help either. Said part's are not available for it anymore. So any ideas guys?

f5 is air pressure sensing failure on these models. check flue, fan and aps.

aps o/n 3003200032
fan o/n 3003200020

 

[mutley racers]

Thanks feller. I shall check these today. Wow, aps is not cheap is it.

 

[mutley racers]

So I was back there today and did all checks. Flue clear, fan coil ok and aps beeps when gently sucking on hose. But, when I open the tap I do not get live on wire from pcb to fan. So does this mean it's the pcb?

 

[lame plumber]

does the aps actually work when the fan is running is more important as it could be either weak fan not activating aps or duff aps, only my little thought, done sucking on aps hoses as I hadnt turned off the gas once on an old ideal with a duff fan, big bang, lots of nervous custards and nil eyebrows, you dont do that more than once!

 

[mutley racers]

I thought that as was noy getting 240volts to the fan then it would be the pcb

Does the aps have 3 electrical connections? If so it has to prove its closed before it will operate the fan. Could be a flow switch not making so not sending the right signal to fire the fan up?

 

[mutley racers]

Only 2 wires going to thr fan. This is only a water heater and not a combi. The dial is showing f5 fault which means a flue problem apparently

 

[mfgs]

APS not fan, is it a 2 wire or 3 wire?

Sorry, I was meant to say 2 going to switch, not fan

Check oh stat is has little to no resistance - beeps on continuity that could be out.

 

[mutley racers]

I didn't see an overheat stat:clown:

overheat stat usually is f1. 9/10 for me its been aps, could be board if your not getting 240v from board. its been a while since working on one. what readings are you getting at aps?

 

[mutley racers]

I am getting continuity through the switch when I suck on the tube. When you say reading on switch, what reading do you mean

 

[giarc00007]

I am getting continuity through the switch when I suck on the tube. When you say reading on switch, what reading do you mean

ohms reading. is it a very low reading?

 

[mutley racers]

I didn't check the aps for resistance. I always believed you just test for continuity

 

[giarc00007]

I didn't check the aps for resistance. I always believed you just test for continuity

if your getting continuity when blowing into it usually fine, mind you i have buggered plenty of them doing this:uhoh2:. a very low ohms reading is also good sign aps is ok. also have you checked venturi?

 

[mutley racers]

Venturi fine. But the fan is not getting 200volts going to it so that makes me suspicious of pcb

 

[giarc00007]

Venturi fine. But the fan is not getting 200volts going to it so that makes me suspicious of pcb

by the sounds of what your saying i would edge towards pcb if not getting 240v at fan and your saying aps is fine. let us know what you decide on and how it turns out. Good luck and sorry cant offer anymore advice.

 

[solutions]

Are you checking fan voltage at the board or at the fan have you checked the fan wiring loom for continuity?

 

[mutley racers]

Are you checking fan voltage at the board or at the fan have you checked the fan wiring loom for continuity?

Checked at the board? Never done a continuity test on a fan and so no. Don't know what a loom is either

 

[mutley racers]

Sorry feller, I do know what the loom is, and I didn't vheck for continuity as no voltage at board

Apparently they don't produce parts for this heater any more. So am wondering if I should get heatline in to do a 1 off repair for a fixed price? Or, do you know where I could get parts? You have been more than helpful feller. It's muchly appreciated

 

[mutley racers]

Just replaces the pcb guys and all is working. As they don't make them any more, it got refurbished for £80. Not bad I thinks
