The bottom drip tray is filling up with water. Water comes from the base of the dishwasher and drips in to the tray. It only happens when the spray arms ar spinning. I beleive it is because the washer in the bottom spray arm is worn.

I can't for the life of me find a washer on its own. Diplomat will only sell the bottom spray arm (inc washer) but not the washer on it's own. No DIY or plumbing stores have one.

Does anyone know where I can get one?

Any help/suggestions would be greatly appreciated

Hi Chris, I do not think the water is coming from the spray arm mount.I expect it is coming from the recirc motor hose and spraying upwards.I have never had a spray arm leak in the base ever.Look at the hose that goes from the motor at the top to the sump, you should feel a split.If so you have to replace the complete motor and this is approx £250 inc vat fitted.All the best.
