Washing machine finally fixed this morning by E&C Domestic Appliances based in Walsall.
Quoted £48 for supply and fit of new rubber door seal and the two clamps to hold it in place. Arrived early (always good). Very polite and didn't mind me watching. Took about 15 minutes. only hiccup was misunderstanding about card payments but took a cheque. Appears only takes cards in shop due to problems with getting a GPS signal for mobile payments. Clear invoice and 5% discount card attached for any future purchase/repair.
