2026-10-30

What Are Error Codes?

Every dishwasher reports anomalies that occur during operation with codes. These codes quickly guide the user to the problem. Error codes are usually three‑digit numbers or letter‑number combinations.

Most Common Error Codes and Their Meanings

• 0-01 / 0-02 (Bosch, Siemens): Water inlet issue – clogged water filter, kinked hose, or low water pressure.
• 0-05 (Beko): Water heating error – heating element faulty or temperature sensor reading low.
• 0-10 / 0-20 (Arçelik): Drainage problem – blocked drain hose, clogged filter, or pump failure.
• E1 / E2 (Bosch): Water leak – water‑level sensor defective or door leaking.
• H1 / H2 (Siemens): Door sensor error – door not closing properly.
• F1 / F2 (Beko): Fan or motor error – motor not engaging.
• R1 / R2 (Arçelik): Electrical error – circuit breaker tripped.

Step‑by‑Step Troubleshooting Guide

Solution steps for each code are listed below:

0-01 / 0-02 (Water Inlet Issue)

• Check the water hose – it may be kinked or pinched.
• Clean the water filter; it is usually located at the top.
• Verify water pressure; problems can arise if it is below 1.5 bar.

0-05 (Water Heating Error)

• Inspect the heating element – is it flashing?
• Test the thermistor (temperature sensor); a very low reading may require replacement.

0-10 / 0-20 (Drainage Problem)

• Examine the drain hose – is it blocked?
• Remove and clean or replace the filter.
• Test the pump; does it make noise?

E1 / E2 (Water Leak)

• Check the door gaskets; replace them if worn.
• Clean the water‑level sensor.

H1 / H2 (Door Sensor Error)

• Close and open the door fully; inspect the latch mechanism.
• Clean or calibrate the door sensor.

F1 / F2 (Fan/Motor Error)

• Manually rotate the motor; if it is stuck, it may be defective.
• Check the electrical connections.

R1 / R2 (Electrical Error)

• Reset the circuit breaker.
• Inspect the power cables; tighten any loose connections.

Preventive Maintenance Tips

Apply the following routines to prevent error codes before they appear:

• Clean the filters weekly.
• Inspect water hoses regularly.
• Replace door gaskets before they wear out.
• Limit use of high‑temperature and high‑pressure programs.

Frequently Asked Questions

• What should I do when an error code appears? First, turn the machine off and on again; if the problem persists, follow the steps above.
• Should I call a professional service? If you cannot resolve the issue yourself, contacting the manufacturer’s service team is the safest option.

Conclusion

Dishwasher problems can be solved quickly with the right information. Understanding error codes and performing basic maintenance extends your appliance’s lifespan and helps you avoid costly repairs.
