Well, the engineer came (and I was polite, never give out to front line staff anything) and also said it was excessive detergent. As Chris says the fact it wasn't water but foam led them to say the machine is just generating too much of it.

I am quite puzzled though. There isn't a previous tenant and this was a new build that came with white goods when I purchased it, so it should be new, and I am quite good at running it with washing machine cleaning products every so often to ensure it's clean.

The last few weeks I have used only one pod but it did, only on occasion as before, do the same thing. The engineer said I should try a different brand of detergent to see if it foams less. This seems odd to me because I'll try it, not sure if anyone has any recommendations on such a brand.
