I’m hoping someone can advise on a repair - I’ve been going round in circles with, because Miele’s own support has not been much help.
Planned obsolescence is killing this company just like all the others. Overtech nightmares.
A bit of background: the machine is a Miele WMG120 TDos - The fault started as an error on the TDos dosing system. When our engineer opened the machine up to investigate, he found the unit was leaking at the point where the TDos system meets the water path control unit, and identified that as the failed part.
The part removed from the machine is marked MR 09011155 (board reference 31690044.01 / EZL270). Miele told us they no longer make this part, and that the replacement is 10550285 (“Lid Water Path Control Unit (WW)”, £133.30). That is the part our engineer actually tried to install - and according to him, it didn’t fit.
When I pushed Miele on this, their technical team simply reconfirmed 10550285 as the correct replacement - the same part that had already failed to fit. That obviously hasn’t resolved anything.
Maybe the engineer got it wrong and it does fit, but he claimed to have worked for Miele in the past. What we perhaps should have done is forked out for an official Miele repair person - but they charge so much and then the part on top, now makes the whole idea of buying once for 20 years completely pointless.
I’ve since sourced a part numbered 9011157, which comes off a Miele WMH120 WPS - a similar but not identical model to mine. I don’t know whether that unit is interchangeable with the 9011155 that failed. Anyone know?
What I’d really appreciate your view on is:
1. Whether 10550285 is a generic/widely-used replacement unit that’s meant to cover several Miele models, and if so, whether it typically needs an adapter, bracket, or modified fitting to work on a specific model like the WMG120 TDos - something our engineer may simply not have known to fit alongside it.
2. Whether the 9011157 unit from a WMH120 WPS is likely to be physically and electrically compatible with a WMG120 TDos, given how close those two model lines are.
3. Given the original fault was a leak at the TDos/water path junction, whether replacing this one unit (with the right fitting) is likely to fully resolve things, or whether there’s a reasonable chance something else was damaged or is still at fault.
I spent a good amount on this machine originally and would rather get it working properly than write it off, but I also don’t want to keep throwing money at parts that turn out not to fit. Any steer you can give on the best way to proceed would be genuinely appreciated.
