Re: Nextra8 HNF 7148 drain pump power problem ?

Thanks for that iadom….., they can repair the board for a tad under £50……., still like to know if i can get away with just replacing the triac though ? lol

Re: Nextra8 HNF 7148 drain pump power problem ?

Thanks specialist, must have been a ghost voltage as you said :(,first time i’ve come across one……, its looks like iadom was right though looking at the pcb, but am at a loss to locate one ?, have had a quick browse online and seem to be able to buy every part except the pcb ?!….., which makes me think its a dreaded DPO (dealer part only) ?, or is it possible to just have the blown triac replaced or will the power surge have caused damage to other components ?

Re: Nextra8 HNF 7148 drain pump power problem ?

Thanks iadom…., yes, just looked again and the 1st triac is blown……, thought it looked funny last night but as i was getting a voltage at the pump end of the wiring i assumed all was well ? is it not possible just to replace it ?….., or has this also caused damage to other components on the board ?

Re: Nextra8 HNF 7148 drain pump power problem ?

Thanks for the replys…., yes specialist01269, as mentioned twice in my post lol….., i tested the pump off the machine on the BENCH lol, although not a professional appliance engineer i have enough transferable experience/knowledge to cope with fault finding lol…., i just wanted to keep my post simple and stick to the known facts but will go into greater detail to clarify for you 😉 ….., removed the pump from the machine,examined it, tested it for continuity and found no problems so turned my attention to the wiring and found arcing damage to the rear of the connector (which could well be what you mentioned in your reply iadom, the motor does show signs of corrosion :wink:) so, checked the cables for continuity, both ok, examined the pcb and found no obvious signs of damage so checked for voltage, assuming that if there had been a short which had damaged the pcb in some way that wasn’t visible i would have no voltage in the cables…, was happy to find i did and put the problem down to the damaged connector, so, replaced the connector and re-connected the pump but, still no joy, so removed the pump again, double checked for continuity , then, as it still checked out i did a mains bench test and the pump ran !.

So, my quandary is this lol…, the motor runs fine when mains tested on the bench….., i have power running through the cables from the pcb to the pump….., so why does the pump not run when connected to the machine ? 😡
