we’d like to explain you how to change the seal ring on your dishwasher. On this particular style of dishwasher, there is a rubber gasket that seals the upper compartment of the pump to the pump body.
If it fails you won’t get good water pressure and therefore you won’t get a good wash. It’s a really easy job the change though, so let me explain you how we do it.
