Bosch Washer Error Code dr:06

The dr:06 code indicates an NTC thermistor relay failure. It is triggered when the washer detects that the water temperature is too high or that the heating relay is stuck in the closed position, meaning the heater cannot be properly shut off. The machine stops operation to prevent overheating damage or a safety hazard.

A power reset may temporarily clear the displayed code, but the underlying fault will almost certainly cause it to return. If the relay is physically stuck closed or the NTC thermistor has failed, the fault condition still exists after a reset. The root cause must be diagnosed and repaired before the washer will operate reliably.

Repair costs vary depending on which component has failed. Replacing an NTC thermistor is generally the least expensive fix, typically falling in the range of $50 to $150 including parts and labor. A relay or control board replacement can be more costly, often ranging from $150 to $400 or more depending on parts pricing and local labor rates.

Diagnosing this error requires running the built-in test P4 and using a multimeter to check the NTC thermistor resistance and relay behavior. A DIYer comfortable with electrical testing and disassembling a washer cabinet can perform these checks. However, if the relay or control board needs replacement, the repair involves working with high-voltage components and is best handled by a qualified technician.

No, you should not continue using the washer until this fault is resolved. A stuck closed relay means the heating element may remain on without control, which poses a risk of overheating the water and potentially damaging internal components. The machine's safety system triggers this code specifically to halt operation and prevent further harm.
