Miele W1724 excess foam repair or replace?

Our Miele W1724 is coming up to 13 years old and it’s led a very hard life. For a little while it’s not always been spinning properly and I can often see there are soap suds being flung around the drum as it tries to spin. The pump impeller is clear and spins. The drain pipe is also clear (has been replaced with another I had laying around). If I let out a small amount of the foamy water via the pump access as it tries to spin it’ll instantly decide to drain more water and then spin properly.

Having seen how much detergent the wife and kids have been using I reckon it’s built up to a point it foams even when we don’t add any, and even on the rinse cycle. I’ve tried running a number of 95deg washes with things like baking soda and washing machine cleaner with little success. Cosmetically the machine has seen better days. It’s noisy, rattles, sometimes the drum will bang into the sides (shock absorbers shot?) and looks like the drum might have dropped a little (worn springs?).

I know some Miele machines can go on for decades but this was one of their cheaper models, and given the issues I’m thinking it’s time to change it but I’ve read Miele don’t make them like they used to? Certainly the 2 year warranty seems ridiculously low compared to the 10 years they gave us on the current one. I’m tempted to go back to a mid range Bosch/Siemens as we had 2 of those prior, although they both ate motor brushes for breakfast.

Any advice gratefully received!
