Hi,

Despite my better judgement I have attempted to rectify a fault with our dishwasher as the chap we normally use is away for a few weeks.

The offending items was pretty much as in this video at 2.26 I.e. the same rubber ring.

https://youtu.be/5kgk_lKLnms?si=D6idVC-Zc6gSoiT3

Unfortunately getting to it was slightly more tricky than the video makes out (isn't it always) and there was additional wiring connected to it. This is where I might have snookered myself. Due to the lack of room and no slack in the wiring harness I've accidently pulled the wires clean out of the connector.

Said connector (JST?) is the red one on this wiring harness but I can't work out how to open it.

Any ideas or suggestions on what I can do instead please? I can prise the connector open a little but not enough to get it a wire in. A bit nervous about apply more force in case I completely break it - not sure I'm doing it right though as its certainly not fully open and ready to receive the two pesky wires.

Thanks in advance.

P.s. its not easy to see where the wiring harness goes so if i can avoid having to open that can of worms and the associated disassembly i would prefer to.

Assuming you've identified it correctly I'd simply buy a cheap box of JST connectors from Amazon and crimp a new one on the end of the wires.

Alternatively a quick search tells me that you can de-pin a JST connector by pressing the visible tab on the pin and pulling it out. Might be a bit trickier without the wire as you'll need to push the pin instead. Not sure what this will accomplish as you'll still need new pins.

You can probably find this or similar in stock at your local electrical shop for pickup tomorrow.

DIY repairs to a metal box containing electricity and water, what could possibly go wrong?

I did a similar thing when the heater packed up on ours. I tried to remove the old pump/heater with the dishwasher upright through the removable panel at the bottom of the front. It was a nightmare and I nearly gave up.

I then turned the whole thing upside down and took the base off which is how you're supposed to access the workings. it was a piece of piss from there.

Ironic on a motoring forum where lots of people do DIY on things that contain explosive fuels, electricity and weigh 1+ tonne. Which then get driven at 70+mph

I had this with an LG washing machine a few months back. Thermistor bust and google suggested x part. Arrived and opened it up, nope its a different part in a different place.

I gave up. BOught a new one £350 off the web. Once you add up downtime, your time, parts you make all that effort onto a 5 year plus appliance.
Its not worth it anymore - not in the UK IMO.

You'd almost think exploded parts diagrams didn't exist to help you work out the right bits ahead of time.

Unless it's something truly terminal I generally try to fix stuff (assuming spares/repairable) because a lot of the time it's just as much time & more money to find an adequate replacement, then get it delivered etc. Especially when it's something that can be fixed in a way where it won't fail again.

Though I guess the threshold varies depending on whether people have the tools & skills to sort it out themselves.

It's not the best picture to work from but to me those don't look like JST/assembled crimp terminal connects, they look like ones where the wire is pressed in from the top? Similar idea to how telephone or ethernet connectors work with the wire pushed down into a slot; cheap, mostly reliable, and prone to pulling or snapping if yanked.

Suspect you can fix it easily (if you know what wire goes where) by cutting back any exposed core, lining the wire up with the slot in the top, then pushing down with something thin & solid.

Hi,

Thanks for the replies and apologies for the slow response, I was away for the night (not because of the dishwasher). My inclination is to repair rather than simply replace (as tempting as that maybe). Partly I'm pretty convinced the original fault was simply down to a washer that is probably a few pence and secondly because what is now the issue surely can't be insurmountable so it seems a waste both financially and environmentally to junk the whole thing.

Here are some detailed photos of the offending item if that helps.









This is in it's slightly opened state



Here are the wires that it needs to be reunited with (note not a single core lots of little wires).



This is the rest of the gubbins for the inlet pipe and the male part of the connector (please excuse the tools of the trade in shot).

Snip off the mating connector and use some wago 221's to reconnect the wires

Thanks - I see the logic but I'm a bit aprehensive about butchering another part. Any downsides/risks in doing this?

The face that you even have a regular dishwasher repair guy tells me you need a new dishwasher.

Sorry my OP may have mislead you there. The dishwasher has been faultless until now.

I'm loathe to condem an otherwise fine dishwasher for 5p washer (now sorted) or a 50p connector which just needs prodding in the right way.

There is a local appliance repair guy who we have used to replace a cooker element twice (one for each side). Of course we should've just bought a new one wink

The terminals in the intact connector look like 1/4" spade connectors, if you have some female spade connectors you could try them and see, or if not ordering a couple to try them won't cost much.
