SMEG DW1710E Dishwasher

[tallpaul]

Just found and became a member of this site, hope you can help. A few days ago the dishwasher started making a loud ‘popping’ sound, it completed its cycle and the wash seems to have been successful. I turned the power off for a while and switched on a few hourd later no sound but although the power LED was illuminated the washer would not operate. I’ve subsequently removed the machine and found that the cause of the noise was the capacitor bridge across the main incoming supply – this has comprehensively blown. Now I’m guessing that this is no more than a smoothing capicitor to accommodate voltage fluctuations – I use them on hifi systems and would not therefore affect the operation of the machine and is easy enough to replace. I’ve checked the two pump motors and the heater element with a meter and all seem ok ie they all showed a resistance (I haven’t at this stage applied any external power). I am assuming the blown capacitor is an indication that something somewhere has shorted out – what doesn’t make sense to me is that the fuse didn’t blow? Any ideas what I might try next?

Replacing the shorted main suppressor will be the only course of action required I would imagine by the sound of it 😀

They just “go” for no apparent reason quite often. Is it just a three leaded plastic encased unit ?

Pretty cheap and easy enough to obtain, an email to spares@ukwhitegoods.co.uk if you’d like one 🙂

As tallpaul appears electrically sound of knowledge; – but for future readers, power off when replacing/checking these please :zap:

Re: SMEG DW1710E Dishwasher

Thanks Dave I’ll try that.

What I’m having difficulty with is why this would make any difference to the operation of the unit since, as you say it is only a supressor, unless I’m missing something with my logic – often the case I might add!

Paul – up late with a dishwasher in bits on the kitchen floor!!

Re: SMEG DW1710E Dishwasher

It’s not a capacitor, although it is a capacitance device. As it is fitted before the mains switch you do theoretically have power to the device at all times. Ultimately they break down and Kaboom. The appliance will run without the suppressor if you wish to prove the point to yourself, expect lines on the telly and crackles on the radio.

Safety first,

….and possibly damage to a computer plugged in nearby!!! 😯

Thanks Penquin45.

I quess that explains why we’ve had to move the radio to the other side of the room in the last couple of weeks!

But still doesn’t explain why the unit wont function at present. How common is it for the cables to ‘go’ between the door controls and the main unit – I’m talking about the ones that have to be continually bent from 180 to 90 degrees?

I have had a few of these where other components have been taken out by the bang, notably on the digital machines (which yours is). Check the loom by all means – the outer door panel has to be removed for full access; exercise extreme caution, as you can shave with the edge of the inner door. Not really a regular problem with these ones, but it can happen. I fear for your digi-board though.

HTH.

I don’t like to ask but if the board has gone west what’s it likely to cost?

[tallpaul]

Re: SMEG DW1710E Dishwasher

Since you mention it are there any simple tests I can carry out to establish if it is the digi-board that’s at fault?

Re: SMEG DW1710E Dishwasher

Not safely I’m afraid. Check your eMail.

Re: SMEG DW1710E Dishwasher

Thanks to Penguin45 and Dave for their kind advice, machine now working following discovery of a faulty cable in the loom between the door and the main unit. Still have to replace the supressor but have that on order. Wife happy, dishes happy – I’m off down the pub – well tomorrow anyway!

Great site. Keep up the good work.
