The dishwasher does not let the water spray through the arms.
If the upper spray arms are not getting water then you will want to check the check ball to make sure that the ball is moving freely. This would cause an issue with the spray arms not getting water. Also check the pump to ensure that there is nothing clogged in the pump and that the impeller is not damaged.
Water keeps running will not shut off would it be water switch and float.
Answer Hello Bear. If it runs without power, replace the valve on the unit. If there is power at the valve, replace the float switch.
How do you check the float?
Answer Hello Gary. If you test across both terminals, with the float down, it should read closed for continuity. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
