ᐅ Siemens Studioline – Have I received all the defective units?

Hello everyone,

I’m feeling a bit frustrated and need to get some thoughts off my chest.

We have been living in our new home for one year now and received a new kitchen. All the built-in appliances in the kitchen are from the Siemens Studioline series, except for the refrigerator, which is from the standard series. The appliances were delivered after a very long wait in October 2022.

From the start, we have had problems with every appliance except the steam oven and the extractor hood. Siemens customer service has already been here several times, but the issues are often not reproducible at the time (demonstration effect?), or the technician fixes something, but as soon as they leave, the problem returns.

By now, I’m really fed up with all these faults and would prefer to replace the appliances, but that’s not so easy (especially financially).

For some issues, I even recorded videos of the faults and showed them to the technician to prove the errors, but since the problems don’t appear while they’re here, they say no fault could be found.

Here’s a list of ongoing issues:

Dishwasher: It makes extremely loud “water pressure noises,” as if too much water is hitting a too-small valve. According to customer service, this is now a known problem. On the first visit, they drilled a larger hole—no improvement. Two weeks later, the valve was completely replaced, with the statement that this was a recognized issue and the valve swap would fix it. However, the machine still makes other louder humming noises, which they now attribute to the zeolite drying system and insist are normal. But in an open living area, this is quite annoying. Later, I found reports online suggesting that a clip or something similar would need to be replaced, but the service technician said he couldn’t do anything about that.

Additionally, for some time now, even after switching dishwasher tablets, half of them remain undissolved in the compartment. In 23 years of using dishwashers, I’ve never experienced this before, and now it happens constantly.

Cooktop: The full-surface induction cooktop automatically detects pots and their position. When I take a pan or pot off the stove— for example, to flip a pancake or pour something off— and then put it back and try to change the temperature, the cooktop does not respond. The display shows the new setting (e.g. level 8 instead of level 3), but the heat stays at the previous setting. I have to turn the cooktop off and on again to adjust the temperature properly. I recorded this issue, but the technician said it was not visible in the cooktop’s error log (which only stores the last 8 cooking processes). Of course, the problem doesn’t happen all the time.

Microwave: During the first use, the microwave made a very loud humming noise. Customer service was called out and found that the fan was defective. It was replaced and worked fine until recently. For about two weeks now, it intermittently makes the same very loud noises again, both during active use and the cooldown phase.

Refrigerator: The fridge works as it should, but after a short time it develops yellowing marks in places where rods or similar parts seem to run along. They suggested this might be caused by a cleaning product I use, but I don’t think so—I’ve used the same refrigerator cleaner for years without issues.

How would you proceed in such a case? Keep pushing customer service until they can reproduce the faults, or just give up and replace the appliances?

The kitchen salesperson sympathizes but can’t do anything and said, “Oh man, it seems like you got all Monday models.”

Sorry for the long text, but I’m really at my wit’s end.
