Dishwasher emergency: heavy light blinking on samsung model – diagnosis and solutions

A blinking heavy light on your Samsung dishwasher can be a frustrating issue. It can indicate several potential problems, and it’s crucial to identify the underlying cause to resolve it effectively. In this comprehensive guide, we will explore the common reasons for this issue and provide step-by-step troubleshooting steps.

Causes of the Blinking Heavy Light

1. Overloaded Dishwasher:

• If you overload your dishwasher, it can strain the motor and cause the heavy light to blink.
• Ensure that you load the dishwasher properly, leaving enough space between dishes for water and detergent to circulate freely.

2. Clogged Drain Pump:

• A clogged drain pump can prevent water from draining properly, causing the heavy light to blink.
• Clear any food debris or clogs from the drain pump filter and impeller.

3. Faulty Water Inlet Valve:

• A faulty water inlet valve can restrict the flow of water into the dishwasher, triggering the heavy light.
• Test the valve by checking for continuity with a multimeter. If it’s faulty, replace it.

4. Malfunctioning Pressure Switch:

• The pressure switch monitors the water level in the dishwasher. A malfunctioning switch can cause the heavy light to blink.
• Inspect the pressure switch and its hose connections for leaks or damage.

5. Defective Motor:

• A defective motor can struggle to pump water effectively, leading to the heavy light blinking.
• Check the motor for any signs of wear, damage, or burning. If necessary, replace the motor.

6. Faulty Control Board:

• The control board manages the dishwasher’s operation. A faulty board can trigger the heavy light to blink.
• Reset the control board by disconnecting the dishwasher from power for a few minutes. If the issue persists, the board may need to be replaced.

7. Other Potential Issues:

• Kinked or crushed drain hose
• Leaking dishwasher door gasket
• Faulty door latch

3. Test the Water Inlet Valve:

• Disconnect the dishwasher from power.

• Use a multimeter to check for continuity between the valve terminals.
• If there’s no continuity, replace the valve.

4. Inspect the Pressure Switch:

• Locate the pressure switch and inspect its hose connections.
• Check for leaks or damage.
• If necessary, replace the pressure switch.

5. Examine the Motor:

• Disconnect the dishwasher from power.
• Inspect the motor for signs of damage or burning.
• If the motor is faulty, replace it.

6. Reset the Control Board:

• Disconnect the dishwasher from power for 5 minutes.
• Reconnect the dishwasher and check if the issue persists.
• If the heavy light still blinks, the control board may need to be replaced.

Resolving Other Potential Issues

• Ensure that the door latch is functioning properly and closes securely.
