Following are methods of dealing with common dishwasher problems. Always keep in mind safety first:
1) Before working on your dishwasher, unplug the appliance from its electrical receptacle or shut off the circuit that powers it.
2) Turn off the hot-water supply valve beneath the sink before disconnecting or working on the dishwasher's supply valve or hose.
3) Don't work inside the dishwasher immediately following a wash cycle; various parts, especially the electric dryer element at the bottom, may still be hot.
