I've recently purchased a used portable dishwasher, one and only to find out that the hose connecting it to the sink has split. How do I replace the hose element? This is two hoses, with the connector to the sink faucet.
Washing appliance problem?
Answers:    Why not ring up the company that sold you the Dishwasher and ask them to pass you a new one.
Or budge to any appliance store and find one.
It should be just screw rotten the old and screw on the latest.
