I would check the water inlet flow rate is fast enough as these will time out if they can't get enough water fast enough.

Try checking the filter for a blockage or pump being jammed with a button , disconnect drain hose at sink hold a few feet off ground over a bucket should pump/ flow quite freely if not then check filter and pump. good luck

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

Un plug machine from wall to see if it re sets.

The LCD display panel needs new capacitors installed,
Get a technician to install new capacitors.

Did you use a big hammer
That will fix it every time LOL.

I get the same problem with a pepeating beep warning. Only solution I've found is to switch it off using off button then switch it back on. It waits a few seconds then finishes the program and drains. The dishes still seem to be quite damp after. Hope this helps

I have a fairly new Hotpoint Aquarius machine (out of guarantee).
When it is switched on, all of the red lights flash and it will not operate.
Can you help please ??

Here are the eco related error codes for your washer..
1)Light 3 (eco) flashes. Water is present in the flood catching tray at the bottom which usually indicates that there is a leak somewhere. More often than not this is just a pipe with a poor fitting and simply tightening the clip is enough to stop the leak. Our machine had a very slow leak from one pipe (not enough to trigger the alarm) which was fixed in this way. The leak is detected by a small float switch located in the flood catch tray.

Undo 4 screws on the metal plate under the dishwasher 3 at the front 1 at the back, this reveals The pump check the seals are in place on the waste pump.

2) Wash indicator lights 3 + 5 (eco + pre) flashing rapidly. Filter is clogged. Pull out the filter and clean it.
3)Runs for approx. 3 minutes and then stops. Lights 3 + 4 (eco and fast) flash. Probably caused by being plumbed into a hot rather than cold water supply. The incoming water is hotter than required for the wash which causes the machine to cut out. Plumbing the machine into a cold water supply will fix the problem with no apparent long term problems.
