What 050124 means on a Cove dishwasher

Error code 050124 on a Cove dishwasher indicates a dangerous power failure condition within the wash pump drive system. The wash pump drive system is responsible for powering the motor that circulates water through the spray arms during a wash cycle. When the control detects an unexpected or unsafe loss of power to this drive system, it flags a "Power Fail Dangerous" error, halting operation to protect internal components from damage caused by erratic or insufficient power delivery.

The most common root cause of this error is a problem with the quality or stability of power reaching the unit. This includes a loose or corroded connection at the wall outlet or junction box, a damaged power cord, or a circuit that is dropping voltage under load. The control board monitors power delivery to the pump drive and will throw this code if it detects conditions outside safe operating parameters, such as sudden voltage drops or interrupted supply.

Beyond the power supply itself, internal faults can also trigger this code. A failing wash pump motor that draws excessive current, a defective motor control board or inverter, or damaged wiring within the pump drive circuit can all cause the control to register a dangerous power condition. Diagnosing this error should begin externally at the power source before moving inward to the pump motor and drive electronics.

Common causes of 050124

  1. 01

    Poor or loose power connection

    Wiring / connection

    A loose plug at the wall outlet, a poorly secured wired connection at the junction box, or a corroded terminal can cause unstable power delivery to the unit. Inspect the power cord and all connection points for signs of looseness, burning, or corrosion.

  2. 02

    Damaged power cord

    Part replacement

    Physical damage to the power cord such as cuts, pinching, or heat damage can interrupt or degrade power to the dishwasher. Visually inspect the entire length of the power cord for any visible damage.

  3. 03

    Voltage drop or unstable circuit

    Wiring / connection

    If the dishwasher is on a circuit that cannot maintain adequate voltage under load, the drive system may lose power intermittently. A licensed electrician can check the circuit for proper voltage and amperage capacity.

  4. 04

    Failing wash pump motor

    Part replacement

    A wash pump motor that is beginning to fail may draw excessive current or stall, causing the control to detect a dangerous power condition within the drive system. The motor may need testing for correct resistance and operation.

  5. 05

    Defective motor control board or drive electronics

    Part replacement

    The motor control board or inverter that manages pump operation can develop internal faults that mimic or cause a power failure condition. This component would need inspection and likely replacement if all other causes have been ruled out.

Frequently asked questions about 050124

What does 050124 mean on a Cove dishwasher?
Error code 050124 indicates a Power Fail Dangerous error within the wash pump drive system. The dishwasher's control has detected an unsafe or unexpected loss of power to the pump that circulates water during the wash cycle. The unit shuts down to prevent damage to the pump and drive electronics. The first step is to check the quality and stability of the power being delivered to the appliance.
Can I fix error code 050124 myself?
Some causes of this error are DIY-friendly, such as checking that the power cord is securely plugged in and undamaged, or verifying that the outlet or circuit is functioning correctly. However, if the problem lies with the wash pump motor or the internal drive electronics, those repairs involve disassembly and electrical testing that are better suited to a qualified appliance repair technician.
Is error code 050124 a safety concern?
Yes, the word "Dangerous" in the error description indicates the control has identified a power condition that is outside safe operating limits. You should not attempt to force the dishwasher to run while this code is active. Investigate the power supply and cord before resuming operation, and if you suspect an electrical fault in your home's wiring, contact a licensed electrician.
Will resetting the dishwasher clear error code 050124?
A reset may clear the code temporarily, but if the underlying cause is not resolved, the error will return. Resetting without addressing the root cause, such as a damaged cord, unstable circuit, or failing pump motor, will not fix the problem. It is important to diagnose and correct the fault before returning the dishwasher to regular use.
How much does it cost to repair error code 050124 on a Cove dishwasher?
Repair costs vary depending on the cause. Fixing a loose connection or replacing a damaged power cord is relatively inexpensive, typically in the range of $20 to $100 for parts and minimal labor. If the wash pump motor or motor control board needs replacement, costs can rise significantly, potentially ranging from $200 to $600 or more depending on parts and local labor rates.
