Sounds like we have the same stove-top. Generally this works well however I confirm that the issue sometimes occurs however not mid-cooking yet!
I do keep the surface meticulously clean between each use (and it gets a LOT of use).
Only use liquid washing-up liquid (fairy) with a sponge to remove all spillage, fat, etc. and then use a dry tea-towel to buff to a mirror shine.
It's about 3 yrs old now and still looks brand new.
Why? The water they use (about 9 liters) must be warmed and filtered a lot.
Take a look at this Video https://www.youtube.com/watch?v=D4n0PUfR78w
Its in English & German.
The plastic part you see is the Heat Exchanger.
This is the problem part of all EU maschines. If you look closely you will see parts of the plastic have turned brown, this is old fat and chalk which is starting to close the water tubes.
The water presure in the washroom comes from these tubes, the less water flow = less presure.
This Heat Exchanger should be cleaned regulary with some form of cleaner.
I use this for eg: Handymatic-Mashinecare https://produkte.migros.ch/angebote/...713.1440944280
It gives also other products (Miele have one)
The Migros have about every 4 months a 50% action, this reminds me it is time to clean the maschine.
Older Dishwashers who used 45 - 50lts of water and up to 10kw electric, did not have a Heat Exchanger.
We also have a water softener in the house, which I've always wondered if it contributes to the problem I have.
And run a "pots and pans" cycle once a month with a product like the Migros one in the photo (on 50% off a few times a year so stock up). You need to run the machine empty (except for this bottle upside down in the cutlery basket - take the sticker off the top of the cap).
Despite cleaning filters etc, they kept coming back.
I made sure I did at least one 70'C wash every week or so although lower temperature washers did clean everything.
But, a couple of months ago, as an experiment, I ran a 70'C wash every day for a week. No more faults and flashing lights.
So that's what we do now - hot pot washes every day or so and it's been fine ever since.
The only thing I've not tried yet, is the cleaning product from Migros.
I'll give it a go over the next couple of weeks and report back.
In the event any other frustrated dish washer user tries this before me, please write your experience here.
While the machine shouldn't be liberal with water usage in order to not put too much of a strain on infrastructure, I see next no reason with them being extra(!) economical with water around here.
What rubbish !
A dishwasher uses far less water than you would use if you washed by hand !
Its dead easy to check, just run the waste water into a 10 litres watering can.
Dishwasher took 12 litres, plus 0.25L of rinsing. It took 90 minutes.
Lesson:
- dishwasher manufacturers take optimal loading instead of average loading
- they ignore average pre-rinse water usage
- they ignore water use with remedial washing for the percentage of items that are not cleaned to satisfaction
- and i'll bet that they use a rather generous amount of water when doing the handwash comparison
you can get whatever result you want.
i guess in normal average use, a dishwasher is comparable to hand washing. esp. for those people who rinse before loading and load the dishwasher sub-optimally.
I can't say I've had any trouble with the dishwasher -- provided I use the 65C mode, not the default 50C eco mode. What I have noticed a huge difference in is the choice of detergent. The stuff from Migros (Handymatic) sadly just does not do a good job, leaving a film on dishes. The detergent I've had the best luck with is, of all things, the cheap 12-in-1 tabs from Denner. I use rinse aid and regeneration salt, both adjusted to the detergent and water hardness, respectively. (People often neglect this. Too much rinse aid will leave a film.)
And yes, you should run machine cleaner periodically. You can get it at any grocery store. Aldi and Lidl periodically have it as a sale item. And you can get it from Bosch-Siemens* or Electrolux, though I'd just buy it wherever it's cheapest and do it more often, as opposed to expensive cleaner rarely.
*When the door hinge on my dishwasher broke, the Bosch-Siemens repairman came and fixed it under warranty. And of course, as part of the repair, started a cycle to make sure it was working properly. As part of that, he ran a bottle of machine cleaner, and told me "Just toss the bottle when it's done, and do it again every 3-6 months. Here's another bottle of machine cleaner." I said thanks and he went his merry way.
Well, a week later I get a bill in the mail for 2 bottles of machine cleaner (the one he used, and the one he left)! I call Bosch-Siemens and explain to the lady on the phone that I was not asked to buy them. (Just to clarify the situation, I was in the other room when the repairman started the test/cleaning cycle, and at no point did he ask if I wanted more cleaner for later, nor was I asked to sign anything at all.) She argues back and forth with me, after a while "offering" to send me a new bill for just the one unused bottle, since I'll need it in a few months anyway. I reiterated that I had not asked to purchase any of it, and that under Swiss law, unordered product may not be billed. So she then says I can mail it back to them. I remind her that under Swiss law, a customer may not be asked to cover the return shipping for an unordered product. So eventually, she agrees to send someone by to pick up the one bottle. Yes, those morons actually sent someone to stop by and pick up a bottle of cleaner they sell for less than 9 francs (and which thus cost them probably no more than 3), surely spending more on labor to pick it up than the bottle was worth, and pissing off a customer in the process, instead of just saying "Oh dear, sorry for the confusion, please accept the cleaner with our compliments."
Now let's see what the results are.
The interior of the machine is sparkling ... not that it was dirty anyway, but it doesn't seem a little cleaner.
The acid test will be to see if the crockery, cutlery, pots, pans, etc. come out consistently clean.
Perhaps I should use the machine cleaner, as it did such a good job cleaning the machine!
What do you think?
