Question about Ariston Technologies LI640S Dishwasher
* My dishwasher appears to fill up with water ok. * Once full it doesn't spray the water over the plates etc. * The timer appears to run as there is a humming sound. * After 10-15 mins it appears the water is pumped out and new water is pumped in. * Still the water is not being sprayed around. * Hence at the end when I open the door I have plates that have not been cleaned at all but it is quite hot inside the machine (looks like the water gets heated but it is not being pumped around to spray on the dirty items). Thanks in advance for any assistance
It sounds like your dishwasher is doing everything normal EXCEPT washing. The unit fills properly, the timer advances properly, the unit drains and goes through a rinse cycle, plus the water is heating. I would check your main wash pump for obstructions that may be clogging it, or if it is not running at all, you need to check the interconnecting wiring and/or something in the wash pump circuit that would prevent it from running. There should be a wiring diagram/tech sheet located behind the lower kick panel under the door. I hope this helps some. Good luck and let me know what you find.

Tips for a great answer:
When the Dishwasher won't fill you'll need to check for the water inlet hose, the water inlet valve and the float switch assembly. When the water fills your dishwasher, a float rises along with it. As the float reaches a certain threshold level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Sometimes it can happen due to float valve and on other occasions due to float switch. Inspect the water hose coming to the dishwasher for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the float switch assembly should be replaced. Hope this helps... Please post back if you need more information.
