Title: Dishwasher faults
Post by: TheBoy on 01 August 2011, 15:39:30
Blows out the RCD (which covers all 3 ring mains :().

Seems to be when well into a cycle, either still when washing, or into drying cycle.

A cold 'prewash' cycle (whatever that is -its a kitchen appliance, me no understandie) works fine.


Is this the normal symptom for a failing heater element?
Title: Re: Dishwasher faults
Post by: TheBoy on 01 August 2011, 15:40:01
Clearly, the element heats up, as it does get hot in the machine before the trip blows

Certainly has to be high on the list. :y

Pull the connectors off the element and check leakage with a megger or failing that a normal ohmmeter.

Check the wiring between the door and main unit as it bends round the door hinge too. All the flexing often causes the wires to chafe.

Just got to work out how to get the sides off.  6 screws, still no further forward ;D

Where is the element, in the sump?

I should add, when its hot and blown the trip, it trips out IMMEDIATELY I turn it back on at the wall.

Once cooled, it appears to be OK again on cold wash, and get 1:30 into a 2:30 wash...

Yep. Should be able to just tip it onto its' front / back / side to get to the element wiring.

A visual check of the element might tell you all you need to know.

Other thing you can go is disconnect the heater and see if the cycle completes. (and then plumb it into the hot water, give Mrs. TB a tea cloth and relax and have a beer in the satisfaction of a successful "repair" and a reduced leccy bill.) :y

Right, without doing anything other than taking the top off, and one of the sides half off, it completes a 'Fast Wash 40C' whatever that means.

Just gonna chuck some plates in to reduce the washing mountain a tad before she gets home...

Is it plumbed into the hot water already??
Coz if not, i dont understand why it can heat the water to 40C and not blow the trip, but it carnt heat it to 65?
I would expect a knackered heater to blow the trip as soon as it turned on.....where as if it is using the hot water, it doesnt need to turn the heater on, as the incoming water temp would be above 40C
Title: Re: Dishwasher faults
Post by: TheBoy on 01 August 2011, 19:27:51
It now bangs the trip as soon as it goes on at the mains. You hear what sounds like a pump start.

Currently popping the trip with wash pump unplugged.  It still pops trip with sump pump unplugged and heater element (a long tube that feeds the upper wash arm?) unplugged.

Need to let the UPS recharge before trying again, else the server will go down next time. Media Center already has the hump...

lol did get a little off topic, i tend to do that!

back to dishwashers, did your empty out before blowing the fuses? mine seems to have left water in so maybe the pump not heater element.
have you looked what currys have in stock in a few stores?
Title: Re: Dishwasher faults
Post by: Kevin Wood on 01 August 2011, 21:02:19
Often there'll be a mains filter on the feed from the mains. Maybe that's gone  leaky? Could be it started just when it had got warm, or when it had the heater load on it, now it's all the time.

You can normally bypass them easily enough for a test.

I can get my head round most things as to how they work.....dishwashers are a complete mystery to me.....with their complicated pipework....i spent days trying to figure what was wrong with my old bosch machine......in the end i decided it was less stressfull, just to buy a new machine  :y

Pushed it back under worktop (minus top/sides/other bits), but something collapsed at the back (guessing the sides give it rigidity).

Job for next week now.

Having proved what it isn't, assuming only one fault, I reckon it narrows it down to wiring or controller.

That said, the join between the top and bottom halves of the main area is furry, so guessing thats weeping a little as well.  Probably best to just buy a new one, and get upset with call centres about delivery :(

Sounds like a spurious leak which gets water onto contacts sometimes and not others.  How are all the seals?

No signs of leaks, maybe a tiny weep from the join in the 2 halves of the main container.  Its new enough to have a tray to catch any leaks, which is bone dry

this model does suffer from burnt wires on the heater box, also the mains filter is a plastic case mains filter that also is a common problem. on this machine you can get liner seals splitting but its not common, main issue with that it fills the steel base plate where the wash pump sits and shorts that out,
sorry tb only just seen your post or would have said earlier.
pm me if need on what you have looked at i used to work on this model.

Part of the problem is I've had a holiday between it not working well, and now.  And drank far too much Keo ::).  So its a bit vague in my mind what was unplugged when I still got it popping the RCD.

Do you happen to have a service manual?

It bangs the trip as soon as the door is closed. I guess the door switch is some kind of interlock for pumps/heaters/solenoids.

As far as I can see currently, the door wiring at the hinge looks fine, and there is no water sat in the tray under the machine.

are you sure its the dishwasher if you have 3 ring mains on one curcuit breaker thats a lot...just a suggestion now winters here do you have more things turned on it could just be your overloading the breaker and by turning on the dishwasher or closing the door which i guess makes some form of connection the curcuit is now overloaded and trips........you could try turning off some other stuff on the curcuit and giving it a go if the dishwasher still works that is :o

Do you have a 13A plug on the cooker circuit? If so, these are often not RCD protected on an installation of the vintage that your is... Might make diagnosis easier when it's not taking out the whole house.

A 500V megger would be a handy diagnostic tool. Don't suppose you have one?
Title: Re: Dishwasher faults
Post by: paul.lovejoy on 10 December 2011, 19:40:38
mind you you said rcd sorry my mistake so assume the 3 ring mains are each on thier own mcb

if you have tried turning of other cuircuits on the same rcd then other itmes on the same curcuit as the dishwasher leaving that on and still trips to confirm its dishwasher i will erm shut up :y

Title: Re: Dishwasher faults
Post by: Ken T on 10 December 2011, 19:47:03
Thing is if you have got it tripping as soon as switched on, something is leaky. My daughter's washing M/C was doing the same thing, I verified this with a PAT tester, and then started unplugging sections until it stopped tripping. It turned out to be the drier element had gone leaky, although it didn't show up as faulty on a DVM, it needed a higher voltage to break down. Spares are available for most consumer goods at a reasonable price.

Title: Re: Dishwasher faults
Post by: Kevin Wood on 10 December 2011, 19:56:34
Element would be my first port of call. If it's got bad enough, leakage between neutral and earth will trip it, then it doesn't need to have actually started heating. A check with a megger would soon reveal the culprit. :y

I didnt have to earlier......i was drilling a hole thro a tile with a wood drill......and leaning on the cordless drill probably a bit too much......i could smell burning and just thought the tile was getting a bit hot.....seconds later smoke came pouring out of the drill....ooopppppssssss..

However since its cooled down it still works......altho it has a slight pong to it  ;D

Just unplug the major components one at a time and use the trip to test.....start with the heater.

Some machines have the element underneath as a heater in rigid-pipe arrangement, others as simple 'kettle' elements laying in the 'bath' of water under the bottom basket.....on the three machines that I`ve had 'go': elements have always been the cause of popping the RCC-breakers........although a leaky rubber element grommet was implicated in one spectacular nocturnal display: "crackin`arcing Gromit!" ;D

Disconnect the element, thus reducing leccy bills, and leave a tea towel next to the machine. Job done. :y

Do you have a 13A plug on the cooker circuit? If so, these are often not RCD protected on an installation of the vintage that your is... Might make diagnosis easier when it's not taking out the whole house.

A 500V megger would be a handy diagnostic tool. Don't suppose you have one?
Here, the 13A on the cooker switch, as well as the cooker itself, is protected by the same RCD.

Element would be my first port of call. If it's got bad enough, leakage between neutral and earth will trip it, then it doesn't need to have actually started heating. A check with a megger would soon reveal the culprit. :y
Certainly wasn't the element in the summer, as it was still banging out with that disconnected.  In fact, by unplugging, I couldn't work out what it was. Ran out of time, went on hols, it had fixed itself by time I got home. 

Just got a meter (digital :() on it from the mains plug.

L-N - open
N-L - open
L-E - open
E-L - open
N-E - open
E-N - strange readings, sometimes a bit like a capacitor, sometimes just rubbish, eg  -14kohms, I suspect an oddity of DVMs

The rectified natural of N-E resistance would be in line with dampness.

H says "...buy a new one! Tight arse, trying to save on heating again"

;D
Not sure I can deal with retarded sales people and retarded call centres.  If I could just drive to Banbury and buy one, thats fine. But I failed miserably in the summer. Most conversations with the inbreds went along the lines of:

Me: I want to take it away today, which of these do you have in stock
Inbred: All of them, sir
Me: OK, I'll take this one
wander off to pay
Inbred: And when would you like it delivered
Me: No, I want to take it now
Inbred: Oh, we don't hold them here, but can get it to you in 10 days

Grrrr

Sorry, I thought I had said what I thought it was when I did the measurements, based on what I (didn't) find in the summer.  I was correct, it was the wiring.

Cycle should have finished, and the laptop still works (wifi isn't on the UPS) :)
