Our Miele went on the blink this last week-end. It's just out of warranty (fume!).

Before I get a man in, and make a huge dent in the bank balance I need to check some of the valves. That means getting to the underneath, which in turn makes me ask...

... is there a standard way to drain the things, so that you don't get water everywhere?

In case anyone's interested, it has an electrically-operated double check valve at the water supply end of the inlet hose - a really wasteful idea. I'm betting this has failed - only 160.00 (plus VAT and carriage) for the part, when an ordinary hose was perfectly adequate before.

Gotta love EU regulations*...

*water byelaws, but introduced because of directive. Utter nonsense.

That's what the last one died of, after ten years or so. It was a Bosch, and I had high hopes of the Miele (the Bosch had several things mended, until I eventually got fed up with bodging it).

I'm hoping it's a blockage or a common part such as an ordinary solenoid valve. Miele spares seem hard to get independently, so if it's bespoke it will be very expensive.

It's a shame as the Miele washing machine we own hasn't missed a beat.

Still, dishwashers aren't complicated, so we'll see.

Hi, Eric

They need to use wires with very fine strands to minimise the breaking, but they don't.

The annoying thing is Pete that years ago the controls weren't on the damn door! Progress they call it!

We recently had a problem with our Siemens dishwasher - full of water. As it was still under warranty I phoned to arrange a repair and was told of a couple of checks to make. However, I first had to empty out the water - removed the filters, used a small ladle and finally siphoned the last bit out with a bit of tubing. I then had to remove a screw from the top of the pump housing and took off the cover to expose the pump impellor. As the guy on the phone surmised there was a blockage (damson stone) wedged in the pump fins. I cleared this and it worked again. (Pump blockages are not covered by warranty!)

Our previous dishwasher (a few years ago) stopped working. When this was looked at it was caused by slight cumulative leakage over time into a built in collection tray. This tray had a lump of expanded poystyrene in it designed to float which hit a safety cutout switch when the water level of 'leakage' into the tray got too high. This was not anything the end user could easilly do but built in to the design!

Well, I was going to make a grumpy post at this point about Miele, but...

... I've just had a follow-up call from the local Miele specialist (Horders in Bristol). Friendly and knowledgeable service guy, who was happy to take the time to explain internal details I was unaware of.

I've now got two possible areas to look at: the double-check solenoid valve on the end of the inlet hose, and the water flow meter inside. The latter is a Hall-effect device - might be tricky to test, but easy to replace if faulty (and the magnet might've fallen off too!). It's an opportunity to give the thing a thorough clean round the door seal too, I guess.

So Horders get points for helpfulness*, and I'll take the cover off to see what's up...

@misterfish: Apparently Miele uses the same floating-polystyrene leak sensor system as Siemens!

*They also said they wouldn't mind just supplying the part, which is also good.

Later...

... it wasn't a Hall-effect switch, it was a reed switch inside. I thinki that's rather a poor choice for that application (rotation sensing), but it looked like it was working when tested on a meter (obligatory woody ref.) using the magnets on the bottom of my Gem Red box.

However, I thought I'd replace it anyway, so got a new one from Maplins (£1.50 - ouch!). When I unsoldered the old one it fell off the board in two pieces - the glass envelope had snapped in half (it wasn't me!). New one fitted, now testing dishwasher, but so far looking good.

Slightly smug, I is... :)

More than I can afford this month, deffo!

My wife's just picked up her car from having a new Diesel injector and turbo boost sensor fitted. The bill was a modest £160, but I had to organise the injector myself - recon one was £190 all-in and a new one would've been £560+VAT. I'm really hoping it's an aberration as the wretched thing has four of 'em!

So no biscuit jointer for me, presently :-(.

The quetion that was most often asked of me was, 'how much is your call out charge?'
I didn't make any charge, I priced according to my costs.
Ten yrs ago Hotpoint were charging £75 to knock on your door.
