Removed power (circuit breaker) and took front of dishwasher off with 6 screws. Disconnected the 2 wires going to the dispenser, removed the 6 screws holding it in and put the new assembly in and connected the 2 control wires. Put the front door on, applied power back to the dishwasher and ran a load of dishes. All worked well and now the dishwasher runs like new.
