RCBO trips with dishwasher

[DieselShunter]

Good job if thats the rascal but i would'nt have thought stalling a motor that tidgy would cause an overload or earth fault.But what do i know,still using the marigolds...

Tend to agree, but he did say it didn't happen till the start of the main wash, which is when the heating element would energise, so to trip the RCBO the fault current would only need to be whatever extra was needed over and above the heater load.

Whatever - he clearly needs to cook the cable ties longer so they're a bit softer in future.

It would appear you are right, it tripped again last night. Starting to lose patience with it now. Might push it off a cliff. I guess that leaves the mains filter or there was a small ceramic like holder attached to the heating element just before the electrical connection of the element that broke. It appeared to draw heat away from the element as the old heating element had no calcium/limescale deposit past that point. Or might just give up. Can you test th mains filter to see if it's broken? Don't fancy buying another part for it and still not curing the problem.

The mains filters are a common problem on this make. espares have them in stock!

This looks a little diffrent to one on my machine. Is it definately the right one?

 

[swifters]

anyone?

with mains filters, the easiest way is just to snip them out of circuit. all they do is stop your machine interfering with TV reception on emmeroids and constipation st. so why bother?

could it cause to trip halfway through though? It alwasy trips at the same point? e.g. when the main wash cycle starts and the motor and element are going at there best.

I know this is no help whatsoever to the op ...... but for a few days now my tumble dryer has been tripping the rcd - until yesterday when it went up in flames ..... :32:

very unlikely. it seems to me that it's motor related. you've replaced the element. time to IR the motor, check for any water leakage. process of elimination. could always take out one of those maintenance contracts, wait a fortnight, then report the fault.

Spoken like a true Scouser !!

my sympathies to tidyboiler. hope she's better soon.

Funny you should say that Tel ..... she's not been well with a bug that's been going around, but she's well on the road to recovery now.

are you sure it's not metal fatigue, lugging copper to the scrappy? :nopity:

Right, this it last chance saloon for this dishwasher. I have disconnected the main filter, am sure there are no leaks, tested the main motor continuity ok and insulation resistance all >200mega ohm. However the motor that drives the waste water pump had some unusual readings. See attached photo... (IR 1.48 mega ohms continuity 63 ohms)

Does that mean the motor is buggered?

 

[swifters]

Forgot to add that I tested it with connectors disconnected

Next step put an independant supply to the motor and try it. Readings arn't bad.
