Eco flashing light and blue flashing light on De Dietrich dishwasher. Dishwasher starts to fill, then lights start flashing and it shuts down.

The beeping sound you are hearing from your Teka DW8 55fi dishwasher is likely related to the "Eco" light. The Eco light is an indicator that the dishwasher is running in the most energy-efficient mode. If the light is flashing, it could indicate that the dishwasher is experiencing a problem with the eco cycle and needs attention.
To troubleshoot the issue, you can try the following:

1. Check if the dishwasher is loaded properly and that there are no obstructions blocking the spray arms.
2. Make sure the dishwasher is level and not vibrating excessively.
3. Check if the dishwasher is properly connected to a working electrical supply and that the circuit breaker has not tripped.
4. Clean the filters and spray arms to ensure proper water flow and performance.

If the problem persists, it may be necessary to call a professional for repair or contact the manufacturer for further assistance.
Please note that these steps are general guidelines and the actual process may vary depending on your specific dishwasher model. It is always recommended to refer to the manufacturer's manual for specific instructions and troubleshooting tips.

1) Ensure the dishwasher is turned off. 2) (may not apply) Turn the plastic blue lever located under the sink to the vertical position (this opens the valve, so water can go into the dishwasher) 3) Pour powder indo the dishwasher 4) Turn the dishwasher controller to the top position (the 12 o?clock position) ? this is the eco-setting. 5) Press the on/power button on the dishwasher, so that it now turned on (a light will display) 6) Move the dishwasher controller to the ?R? position (it?s on the very left), and leave it there a second or two. 7) Move the dishwasher controller back to the eco-setting (the 12 o?clock position).

if the eco light is flashing, this indicates that saftey float switch has activated in the base of the dishwasher usually caused by a leak, a polystyrene float activates a microswitch which cuts of the water inlet supply

the heater is faulty.

Check pump is running

Pull the built in unit out and tilt towards the rear right leg and the water will drain on to the floor. The Dishwasher then restarts but the anti flood sensor will reactivate after 2-3 more washes. Do not know final fix yet.

I too had this problen today. Printed off a manual from the Hotpoint website. Very helpful troubleshoot section. Anyway, flashing eco and fast lights and beeping sound indicates 'water feed pipe blocked' You need to check the water inlet connections on your tap.However, when we pulled it out we noticed the blue water inlet pipe was slightly kinked. Straightened this out and hey presto! It works fine again. How this happens when its worked ok for 18 months will never know but still. Try it! hope this was helpful...shewoo
