Error Code E01

The Blomberg Dishwasher error code “E01” signifies a drainage issue, indicating that the dishwasher is having trouble effectively draining water. This could be due to a clog or blockage in the drain system, which includes the drain hose, filter, or connection to the garbage disposal.

Possible Causes:

  • Clogged Drain Filter: The dishwasher’s drain filter, designed to catch food particles and debris, might be clogged, restricting water flow.
  • Blocked Drain Hose: The hose that carries waste water from the dishwasher to the drain system could be kinked or clogged with debris.
  • Garbage Disposal Issues: If the dishwasher drains through the garbage disposal, a blockage in the disposal or an improperly installed drain plug can prevent proper drainage.
  • Pump or Drain Valve Malfunction: The pump or drain valve, which helps push water out of the dishwasher, might be malfunctioning or obstructed.


  • Clean the Drain Filter: Remove and clean the dishwasher’s drain filter according to the manufacturer’s instructions, ensuring it’s free of debris and food particles.
  • Inspect and Clear the Drain Hose: Check the drain hose for kinks, bends, or clogs. Straighten any kinks and flush the hose with water to remove blockages.
  • Check the Garbage Disposal: If connected to a garbage disposal, make sure it’s clear of food waste and running correctly. Ensure any disposal inlet plugs were removed during dishwasher installation.
  • Examine the Pump and Drain Valve: Look for obstructions in the pump or drain valve that might be preventing proper drainage. Consult the dishwasher’s manual or a professional for guidance on checking these components.
  • Reset the Dishwasher: Try resetting the dishwasher by turning it off at the power source for a few minutes. This can sometimes clear minor electronic glitches affecting the drainage system.
  • Professional Assistance: If the issue persists after these steps, it might be necessary to seek professional help. A qualified appliance repair technician can diagnose and repair more complex issues with the pump, drain valve, or other components.

Error Code E02

The Blomberg Dishwasher error code “E02” indicates a Water Filling Problem, signifying that the dishwasher is encountering difficulties in filling with water to the required level for a wash cycle. This issue can affect the appliance’s ability to clean dishes effectively and may result in incomplete cycles.

Possible Causes:

  • Low Water Pressure: Insufficient water pressure in the home’s supply can prevent the dishwasher from filling properly.
  • Clogged Inlet Hose: The hose that supplies water to the dishwasher could be blocked with sediment or kinks, restricting water flow.
  • Faulty Water Inlet Valve: The valve that controls the flow of water into the dishwasher might be malfunctioning, not opening fully or at all.
  • Blocked or Misaligned Filters: Filters within the water inlet path could be clogged or improperly installed, hindering water entry.


  • Check Water Pressure: Ensure that the home’s water pressure is adequate for the dishwasher’s requirements. You may need to consult with a plumber if water pressure is consistently low.
  • Inspect and Clean the Inlet Hose: Examine the water inlet hose for kinks, bends, or clogs. Straighten any kinks and flush the hose to remove sediment or blockages.
  • Test the Water Inlet Valve: Use a multimeter to test the inlet valve for continuity. A lack of continuity suggests that the valve is faulty and needs replacement.
  • Clean or Replace Filters: Check any filters within the water inlet system for debris or improper installation. Clean or replace them as necessary to ensure unobstructed water flow.
  • Reset the Dishwasher: Disconnect the dishwasher from power for a few minutes to reset the appliance. This can sometimes resolve minor electronic issues affecting water intake.
  • Professional Diagnosis and Repair: If the water filling issue persists after these steps, professional help may be required. An appliance repair technician can provide a comprehensive assessment and address more complex problems like a faulty water inlet valve or issues with the dishwasher’s control system.
Resolving an E02 error in a Blomberg Dishwasher involves ensuring that the appliance can receive an adequate supply of water through a clear and functional inlet system. Regular checks and maintenance of the water supply line, inlet valve, and filters can help prevent filling issues and ensure the dishwasher operates efficiently.

Error Code E03

The Blomberg Dishwasher error code “E03” indicates a Heating Element Fault, meaning the dishwasher is experiencing issues with heating the water to the required temperature for the selected wash cycle. Proper water heating is crucial for achieving optimal cleaning results and activating detergent effectively.

Possible Causes:

  • Faulty Heating Element: The heating element may be damaged, malfunctioning, or have a bad electrical connection, preventing it from heating the water.
  • Malfunctioning Thermostat or NTC Sensor: The thermostat or NTC (Negative Temperature Coefficient) sensor, which monitors water temperature, might be failing to accurately gauge or control the temperature.
  • Wiring Issues: Problems with the wiring connections between the heating element, thermostat/NTC sensor, and the main control board can disrupt heat control.
  • Control Board Failure: The dishwasher’s main control board could have a fault preventing it from properly activating the heating element or interpreting temperature sensor readings.


  • Inspect the Heating Element: Check the heating element for visible signs of damage such as cracks or breaks. Use a multimeter to test for continuity. If damaged, it will need to be replaced.
  • Test the Thermostat/NTC Sensor: Verify that the thermostat or NTC sensor is functioning correctly. These components should offer resistance changes in response to temperature changes; if not, replacement may be necessary.
  • Examine Wiring and Connections: Inspect the wiring and connectors related to the heating element and temperature sensors for any signs of damage, wear, or loose connections. Repair or replace as needed.
  • Reset the Dishwasher: Sometimes, resetting the dishwasher by disconnecting it from power for a few minutes can clear minor electronic glitches that might be affecting the heating function.
  • Seek Professional Repair: Due to the complexity of diagnosing and repairing heating element issues, which involve electrical components and potentially high voltages, it’s advisable to seek professional assistance. A qualified technician can safely assess and fix the problem.
  • Consult the User Manual: Refer to the dishwasher’s user manual for any specific troubleshooting steps or reset procedures recommended by the manufacturer for dealing with heating issues.
Addressing an E03 error in a Blomberg Dishwasher involves ensuring the heating element and its associated components, like the thermostat/NTC sensor and wiring, are in good working order. Given the technical nature of these repairs, professional service is often recommended to ensure the issue is resolved safely and effectively.

Error Code E04

The Blomberg Dishwasher error code “E04” indicates a Door Interlock Fault, meaning that there is an issue with the dishwasher door not being properly closed or a malfunction in the door interlock mechanism. This safety feature ensures that the dishwasher does not operate unless the door is securely closed and locked.

Possible Causes:

  • Door Not Fully Closed: Obstructions or misalignment might prevent the door from closing completely.
  • Faulty Door Latch or Interlock Mechanism: The mechanism that locks the door could be damaged, worn, or malfunctioning, preventing it from engaging properly.
  • Damaged Door Seal: A damaged or obstructed door seal can hinder the door from closing fully.

Addressing an E04 error involves ensuring the dishwasher door can close and lock properly, which may require cleaning, adjustments, or part replacements. Due to the safety implications of a malfunctioning door interlock, it’s important to resolve this issue promptly to ensure the dishwasher operates safely and effectively.
