*** Steam Oven ***
After 12 months it lost its non-return valve from the water tank. To their credit, the shop replaced the tank with a new one, but the valve again fell out again after 6 months.
When steam oven oven heats up, the small fan which initially emits a quiet hum, changes to a rattling noise which continues until the oven has cooled down.
*** Plate warmer ***
After warming up it starts to emit an annoying buzzing noise, which continues until you switch it off.
*** Dishwasher ****
This is by far the worst dishwasher I've ever encountered.
It doesn't seem to matter what combination of salt, rinse agents, tablets, powders, washer boosters, temperature settings, water hardness settings I use, the results are generally extremely poor.
When I returned to shop to obtain the replacement faulty water tank for the steam oven, I mentioned this to the guy in the shop and he admitted that he had the same problems at home with his Siemens DW and he thought it was due to the minimum amount of water the machine is using!!!!
Furthermore a colleague at work recently renovated her kitchen (in France) and I warned her about the Siemens dishwasher problems. Unfortunately for her, she had already received a Siemens machine ... now 6 months on, she is also cursing this crap appliance.
We both agreed that the only way to get half decent results is to use the hottest "pot wash".
What is even more frustrating, is that I've used far cheaper machines, which time and time again, produce excellent results.
I should have taken my German colleagues advice, which was "If it involves water, always buy Miele", hence when I recently bought a washing machine, I paid the extra and I've never regretted it ... outstanding machine.
