Spray rinse between the 3rd and 4th rinses

On my early Model Miele, you get a spin spray.

The machine gets up to 900RPM for 2 minutes and then the fill valve opens which results in water spraying over the door and outside of the inner tub, (I assume to remove an build up of suds and/or soap scum from between the tubs) It maintains this for 30 seconds, and then cuts the pump and spin motor and coasts to a stop with the fill valve running the whole time.

So Whilst its not spraying directly into the tub, there is a fair amount of water that makes in in there from the spray off the door glass back into the tub. Because it does 5 rinses getting rid of the foam is probably more important than spraying the clothes.

The Miele can suds lock badly. By default, at the end of the wash, it fills with water halfway up the glass to do a suds cooldown. It then drains, high level Fills (1/3 of the way up the glass), and tumbles for 5 minutes. It then repeats the process. Its not until after the third rinse that the machine tries to spin for the first time.

Smart me figured at one point, that after the wash pumpout, I'd advance it to spin to try and remove more soap and suds earlier in the wash sequence. Unfortunately all I acheived was a spin that got nowhere up near 900rpm, and a tub full of very creamy suds (Like stiff eggwhites) Since then I've respected its no spin rinses as definitely necessary.

I hope this isnt too off topic.

No Nate that is fascinating

I have noticed the newer FL from after the 90's onward here and earlier in Europe have a very narrow gap between the inner tub and the outer tub. I get the impression designers felt the larger gap just used more water and made the machine bigger.

But I also found Bendix did extensive testing of tub gap in the late 1930's! They found and patented a gap that by today's standards was large.
They state their gap allowed a wash current to be created by the outer surface of the inner tub that lifted water and suds up from the sump to be redistributed down through the clothes as they tumbled inside the drum. They even set the maximum and minimum dimensions for this gap it was so important to them. It is about an inch or more between tubs!

The Maytag Neptune had such a close gap that the tubs almost look like they touch and detergent was getting locked in an eddy current in the sump so clothes weren't getting as clean so later models introduced a sump pump to pump the detergent rich water from the sump up to the fill flume and back into the tub.

I bet the larger gap would allow a spin spray, I'm going to try it in my Bendii.
Nate do you know what the tub gap is in your Miele??

maybe Jaimie can

measure the tub gap in his NEW Honeycomb Miele for us??

Tub Gap

Hi Jon,

The 70's model Miele has a distance between the inside surface of the wash tub to the outer tub of 3cm.

My almost current model Honeycomb drummed Miele has a distance of 2cm between the inner and out tubs. The new machine does a 1200RPM spin between the wash and each rinse. The final spin is 1200 RPM for 6 minutes and an 1800RPM spin for 2 minutes.

Jon that was so neat!!! Aren't you so thankful that we aren't stumped by "double trouble" on washdays!! You just have to love the styling on those beautiful machines.
