Miele Dishwasher Issues

[brisnat81]

Have you been playing with the settings on the machine, prior to this starting?

I increased the water level on our G6905 and it’s now using 15-25l on a sensor wash. So I’m just wondering whether you’d made any configuration changes prior to this change in consumption. 25l seems to be the upper limit, I’ve never seen it go above that.

Tom

Is the first service menu for service parameters and the second one for the programming menu?

I have a 6987(USA model) and the only time it started taking about 22 liters of water for a program was when I switched detergent to Cascade Action Pacs. The suds in the detergent caused the machine to draw water several times during the wash, interim rinse, and even the final rinse. Changing detergents returned the usage to normal.

Really hope your new part will solve this problem.

Hey Brisnat81 - I haven't changed any settings on the machine - I only found out how to access the service menu after the machine started playing up to read the error codes. The increased water level setting is turned off.

Jerror_Si - it could be - one menu has the component and switch tests, and the other has the increased water level and increased water temp.

I've been using the same dishwasher detergent since before I got the dishwasher, and as far as I know, the formulation hasn't changed. It's low foaming and clean rinsing.

I took a picture whilst it was mid-wash last night, it's definitely heating up as the water is hot, but you can see how much water is in the bottom.

Wow

Yes, that is a lot of water since it normally only covers the filter area. It's got to be something that is making the machine think it needs to add more water so I Hope the replacement part will fix this problem.

When it is washing

Do you hear water being sprayed with force or just a weak spray?

Water softener

Could the water softener have malfunctioned, or been perhaps mis-adjusted by the user?

On my Bosch (circa 2004) it says in the manual that higher settings of the water softener will cause water consumption to increase.

Which brand of detergent are you using? Some do create excess froth, which causes the machine to keep topping up.

Have you tried running a Dishwasher Cleaner (the liquid in bottle version) through a cycle or two?

The higher water usage with higher water softener settings is due to the more frequent water softener regeneration cycles.

The water softener has to be flushed after a certain amount of water has to be softened.
The harder the water the more frequent that happens.

For example, our old BSH DW had to run a regeneration each cycle with the extremely high water hardness at my parents place.
My DW here only runs a regeneration cycle every 4 cycles or so.
Both machines used about 4l for the regeneration - but since that water contains lots of minerals, its just drained immediately.
