This confusion can lead to an error state and the blinking start light.

Try pressing the button firmly several times to see if you can dislodge any debris or correct a sticky mechanism.

Water Inlet Valve Problems

The water inlet valve is responsible for controlling the flow of water into the dishwasher. If this valve is malfunctioning or obstructed, the dishwasher may not receive an adequate water supply.

Insufficient water flow can trigger the blinking start light, as the dishwasher detects an anomaly during the filling process.

A clogged or faulty valve can restrict water flow, leading to a low-water error.
Check the valve for any visible signs of damage or blockage.
Also, ensure that the water supply line is properly connected and that the water supply is turned on.

Drain Pump Blockage

The drain pump is crucial for removing wastewater from the dishwasher after each cycle. If the drain pump is clogged with food particles or other debris, it can prevent the dishwasher from draining properly.

A clogged drain can cause water to back up into the dishwasher, triggering the float switch or other error sensors.

The resulting error state will manifest as a blinking start light. Carefully inspect the drain pump area for any obstructions.

Float Switch Issues

The float switch is a safety mechanism designed to detect overflowing water inside the dishwasher. If the float switch malfunctions, it can send false signals to the control board.

A malfunctioning float switch might indicate an overflow situation even when the water level is normal, triggering the blinking start light.

Ensure the float switch moves freely and is not obstructed by debris. A stuck float can cause the dishwasher to behave erratically.

Now that we’ve explored what the blinking start light signifies and how error codes can offer clues, let’s delve into the usual suspects behind this frustrating issue. Pinpointing the exact cause is the first step towards a successful resolution.
