Hello everyone,
I have been registered to this website for a long time, though I seldomly posted.
I recently bought a second hand Mìele G7310 dishwasher from Facebook Marketplace. With it being only 200€ and 4 years old I knew it had to be mine.
I already had experience with a Mìele G5500SC and a G5830SCU model which both worked brilliantly. My main dishwasher is a Serie 6 Bosch built in 2021
I also quite like dishwashers and have owned/resold at least 8 of them in the past year or so. The oldest one I own is a REX (ZANUSSI) IP760N from 1993, a brilliant and solid machine
A couple of things to consider beforehand:
1. I NEVER rinse the dishes before loading the dishwasher. I'll typically use a spatula or a paper towel to remove solid residues and large amounts of sauce, then everything goes into the machine. It's called a dishWASHER, NOT a dishRINSER!
2. I tend to alternate different brands of detergent such as Somat (Pril in Italy), Svelto (P&G product), Fairy/Jar but all in tabs form. I do not like liquids as they can't remove tomato sauce/tea/coffee stains since their formulation does not contain any bleaching agents. I have also used Mìele's own PowerDisk in some tests
3. I will typically run long cycles, not short ones, as the machine usually runs overnight
4. I load the dishwasher quite a bit but making sure water can reach all the dishes
With this being said, I think this is the worst performing dishwasher I have ever used.
QuickPowerWash simply splashes tomato sauce and various residues on expresso cups
PowerWash does the same, albeit taking much longer (2h30) and using 23L of water + 1.4kWh of energy. For reference, this is how much water and energy my REX IP760N from 1993 uses, yet the latter washes perfectly
Auto washes decently, but runs for a long time (3 hours). Still, espresso cups on the shelf can't seem to come out clean
I have yet to try the "Extra Clean" option and Intensive, ECO, Glassware and Hygiene cycles
Thing is, the machine is VERY inconsistent with its wash results, so I have tried adding a 2nd interim rinse, with poor results. It can't remove stuck on pasta on a pot with a 2h+ cycle and it sometimes leaves residue on dishes
However, when it washes, it washes well
I think it's all down to poor programming and poor spray arms design: the upper spray arm can't reach the corners of the basket and the lower one runs for only 20 seconds at a time. Then, the machine switches to the center spray arm for 40 seconds, then upper for 20, and so on. Why? Dirtiest items are in the bottom basket
Anyone with a G7XXX dishwasher having the same problems as me? Maybe I'm at fault, but all other machines I have used coped well with this type of soiling.
With my Bosch, the Auto cycle is sufficient for most loads. With the REX, the 55°C Economy cycle suffices, but how can a 2020 machine that uses a LOT of water and energy for modern standards NOT wash well?
When entering programming mode I noticed I can set a country variant: mine is set to EU1, but EU2, JPN, CN, AUS and USA are other possible choices. Maybe I can set it to EU2 and it will wash better? Don't know, can someone explain to me what these settings do?
Sorry for the rant, I am sure I will receive precious help from the forum members.
Attached are some pictures of loads with before/afters.
Cheers
