9. Damaged Flow Meter

Cause

The flow meter of your Indesit Dishwasher plays a crucial role in managing water flow and the overall operations of the machine. 

A damaged flow meter can cause the flashing lights 1 and 3 on the dishwasher. This is typically due to prolonged usage, rough handling, or even manufacturing defects. 

The flow meter may not accurately measure the amount of water that enters the dishwasher, leading to under or overfilling. 

This can disrupt the wash cycles and damage your utensils or the dishwasher itself.

If these sensors are covered in grime or food particles, they may falsely signal that the water is dirtier than it actually is, causing the dishwasher to run longer than necessary or to stop prematurely.

Solution

The solution to this problem is relatively simple: clean the sensor. 

Unplug the dishwasher, locate the sensor (usually found at the base of the unit), and gently clean it using a soft brush and warm, soapy water. 

Rinse thoroughly and dry before reconnecting the unit. Regular maintenance and cleaning of the sensor can prevent this issue from recurring.

14. Incorrectly Loaded Dishware

Cause

If your Indesit Dishwasher’s lights 1 and 3 are flashing, one possible cause could be incorrectly loaded dishware. 

This can happen when dishes or utensils are not properly placed in the racks, blocking the water spray from reaching all items. 

This leads to inefficient cleaning and could trigger the dishwasher’s sensors, causing the flashing lights.

Key takeaway: The dishwasher needs clear pathways for water to reach all dishes. Incorrect loading can obstruct these pathways and lead to inadequate cleaning.

Solution

The solution to this issue is rather straightforward – you need to pay attention to how you load your dishwasher.

Ensure that larger items, like pots and pans, are not blocking smaller items like cups and utensils. Additionally, make sure that no item is obstructing the spray arms from rotating freely.

Remember: Properly loading your dishwasher not only ensures cleaner dishes but also prevents unnecessary wear and tear on your appliance.

15. Short Circuit in Control Panel

Cause

A short circuit in the control panel of your Indesit dishwasher typically arises due to a power surge, faulty wiring, or water ingress. 

This can lead to the dishwasher malfunctioning, represented by flashing lights 1 and 3. 

A short circuit disrupts the normal flow of electricity, causing the control panel to behave erratically.

Wiring faults or water exposure are common initiators of a short circuit. A power surge can also lead to this issue. 

Malfunctioning represented by flashing light indicators is a red flag for a possible short circuit.

Solution

Addressing a short circuit requires careful examination and often professional help. 

Start by disconnecting the dishwasher from the power supply to ensure safety. Inspect the control panel for visible damage or moisture. 

If the issue persists, it is recommended to call a professional technician for a thorough examination and repair.
