Hi, I have an Ariston LL64 model dishwasher that doesn't complete a wash cycle. It gets so far and stops with the "crystal care" light flashing. Any ideas? thanks Barry

Error messages:
Your dishwasher is equipped with a safety system which is able to detect any operating anomalies. These anomalies are reported by one or two wash cycle indicator lights "E" flashing rapidly.
Flashing Led diode below button with the image of wine glasses means faulty thermistor NTC. So, could be faulty: thermistor NTC (defective or not positioned), wiring, control board.

Your dishwasher is equipped with a safety system which is able to detect any operating problems. These anomalies are reported by
one or two wash cycle indicator lights "E" will flash rapidly.

Any flashing combination of LED diodes (Intensive wash, Regular wash, Eco wash, Rapid wash, Soak and Crystal care) means different error code. Take a note of which lights are flashing?

If you have problem with fill water than following two LED should be flashing.
In this case could be:

• Water valve disabled
• Turbine disabled
• Control board faulty

make this test and fix it. God bless you
1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

This model doesn't use a timer like older types, The element is turned on and off by the electronics and a failed board can cause the symptoms mentioned, thee is no real way to test the board as the integrated electronics are quite complicated. The board is easy to replace, if you can use basic tools you would be able to manage it.
The dishwasher is cold fills so heats it's own water so the hot water temperature in the house has no impact on the dishwasher.

You did not mention what model number that you had but this is what I found after a little digging:

From http://servicetechhelp.com/discus/messages/2801/6823.html?1205974228 :
For future reference, the technician who replaced the control board for me gave me a complete list of flashing LED fault codes for the Ariston LL65 (which are same as Ariston LL64):

001000 Float Switch: Water in Base Pan
001100 No Drain: Dranin Motor Disabled, Filters Clogged, Dramin Hose Blocked
001010 Main Motor Presure Switch Blocked Filter
100100 Control Board: Software of Control Board not Recognized.
000100 Water Valve: Water Valve Diabled <--- This one sounds like your error
000110 Fill Fault: Water Valve Disabled, Turbine Disabled or Control Board
000101 Heating Element disabled or High Limit Open or Control Board
000010 NTC defective or not positioned or control board
000001 NTC defective or not positioned or control board

KEY: 0 = LED off
1 = LED flashing


I also found this for a different model:
