Panasonic Error Codes & Diagnostics

Access our premium database of error codes, common faults, and professional repair solutions for Panasonic appliances.

Luxury front-loading washing machine in brushed titanium with illuminated dark glass drum
CodeAppliancesFault / DiagnosticsRepair InstructionsAction
F82
Oven / Microwave
NTC Temperature Sensor & Thermistor

Oven not heating correctly or overheating.

The oven temperature sensor (thermistor) has an open circuit, meaning it's broken or disconnected.

Unplug the oven. Access the temperature sensor inside the oven cavity, check its wiring, and test it with a multimeter. Replace the sensor if it's faulty.

Diagnose
H01
Washing Machine
Water Level Pressure Switch & Air Dome

Machine stops, fill or drain error.

A fault with the water level sensor (pressure switch). The sensor is not correctly detecting the amount of water in the drum.

This is typically an internal fault. Check the wiring connecting to the pressure sensor. The pressure tube may be blocked or disconnected. The sensor itself may have failed and requires replacement by a technician.

Diagnose
H05
Washing Machine
NTC Temperature Sensor & Thermistor

Appliance is not functioning, error code displayed.

Data error in the main control board's memory. Can also indicate a faulty temperature sensor in the freezer compartment for refrigerators.

Try unplugging the appliance for 10 minutes to reset the control board. If the error returns, the main control board or the relevant sensor needs to be replaced.

Diagnose
H07
Washing Machine
Drive Motor, Inverter & Tachometer Sensor

Motor not turning or spinning erratically.

The tacho sensor on the motor is faulty or has a poor connection, preventing the main board from reading the motor speed.

Unplug the appliance. Check the wiring harness between the motor and the control board. The motor or the tacho sensor may need to be replaced.

Diagnose
H09
Washing Machine
Electronic Control Board (PCB) & Bus Communications

Machine is dead or unresponsive, error code displayed.

Communication error between the main control board and the display board.

Check the wiring connections between the two circuit boards. If connections are secure, one of the boards has likely failed and will need to be replaced.

Diagnose
H21
Dishwasher
Drive Motor, Inverter & Tachometer Sensor

Appliance not working, error code displayed.

For dishwashers, this indicates a water leak. For refrigerators, it indicates an ice maker malfunction.

Dishwasher: Check for leaks in the base pan. Refrigerator: Check the ice maker for jammed ice, inspect the motor and sensors.

Diagnose
H23
Washing Machine
Heating Element, Thermostat & Safety Fuse

Machine trips breaker or doesn't heat water.

A fault in the heating circuit, typically a heater relay on the main control board has failed.

This is a fault on the main PCB. The board will need to be professionally repaired or replaced.

Diagnose
H24
Dishwasher
NTC Temperature Sensor & Thermistor

Dishes are not cleaning properly, water is cold.

Water heating fault. The dishwasher is unable to heat water due to a faulty heating element, thermistor, or control board.

Requires service by a technician to test the heating element and associated components for continuity and resistance. Replace faulty parts.

Diagnose
H27
Washing Machine
Door Lock Mechanism & Safety Interlock

Door will not lock or unlock.

The door lock mechanism is jammed or has failed electrically.

Check for obstructions around the door lock. If clear, the door lock assembly needs to be tested and likely replaced.

Diagnose
H29
Refrigerator / Freezer
Drive Motor, Inverter & Tachometer Sensor

Refrigerator is not cooling properly, may be noisy or too quiet.

The fan motor in the refrigerator compartment is not working, preventing cold air circulation.

Check if the fan blade is blocked by ice or an object. If it spins freely by hand but doesn't run, the fan motor has likely failed and needs to be replaced.

Diagnose
H35
Refrigerator / Freezer
Refrigeration Compressor, Defrost Heater & PTC Relay

Refrigerator is not cooling at all in either compartment.

Cooling system fault. This indicates a serious issue with the sealed system, such as a refrigerant leak or compressor failure.

This error requires a certified refrigeration technician. Do not attempt to repair it yourself. The system will need to be diagnosed, repaired, and recharged.

Diagnose
H43
Washing Machine
General System & Mechanical Integration

Machine stops mid-cycle and displays error.

A water leak has been detected in the base of the machine, activating the flood protection sensor.

Unplug the appliance and inspect for the source of the leak. Check hoses, pump seals, and door gasket. Dry out the base pan to reset the sensor after fixing the leak.

Diagnose
H50
Refrigerator / Freezer
Refrigeration Compressor, Defrost Heater & PTC Relay

Excessive frost buildup in freezer, poor cooling.

The defrost system has failed, often due to a faulty defrost sensor not detecting ice buildup on the evaporator coils.

Manually defrost the unit. The defrost sensor needs to be tested and likely replaced. Also check the defrost heater and thermostat.

Diagnose
H51
Washing Machine
Drive Motor, Inverter & Tachometer Sensor

Machine struggles to spin, stops during cycle.

Motor overload. The drum is too heavily loaded, or there is an issue with the motor or motor control board.

Reduce the size of the laundry load and try again. If the error persists with a normal load, there may be a fault with the motor or main PCB.

Diagnose
H97
Oven / Microwave
Drive Motor, Inverter & Tachometer Sensor

Microwave does not heat, may make a loud buzzing noise.

Fault with the high-voltage inverter board or the magnetron. This is common in Panasonic inverter microwave ovens.

High voltage is extremely dangerous. This repair must be performed by a qualified technician. The magnetron and/or inverter board will need to be replaced.

Diagnose
H98
Oven / Microwave
General System & Mechanical Integration

Panasonic H98: Water/air heating failure in Oven / Microwave; heating circuit does not reach set temperature.

Indicates a magnetron failure. The microwave-generating component is no longer functioning.

This is a high-voltage component. For safety, the repair should be handled by a professional. The magnetron needs to be replaced.

Diagnose
U11
Washing Machine
Drainage System & Drain Pump

Machine will not drain water.

The drain pump filter is clogged, the drain hose is kinked or blocked, or the drain pump has failed.

Unplug the machine. Check and clean the drain pump filter located at the bottom front. Ensure the drain hose is not bent, kinked, or blocked. If the issue persists, the drain pump may need to be replaced.

Diagnose
U12
Washing Machine
Door Lock Mechanism & Safety Interlock

Washing machine will not start or stops mid-cycle; door open error.

The door or lid is not fully closed and latched. The door lock mechanism may be faulty.

Open and close the door firmly to ensure it is latched. Check for any clothing or objects obstructing the door seal. If the error continues, the door lock assembly may need service or replacement.

Diagnose
U13
Washing Machine
General System & Mechanical Integration

Machine stops before or during the spin cycle.

The laundry load is unbalanced inside the drum, causing excessive vibration.

Pause the cycle, open the door, and manually redistribute the clothes more evenly inside the drum. Avoid washing single heavy items. Restart the spin cycle.

Diagnose
U14
Washing Machine
Water Inlet Valve, Aquastop & Flowmeter

Washing machine is not filling with water.

The water supply tap is turned off, the inlet hose is kinked, or the water inlet valve filter is blocked.

Ensure the water supply tap connected to the machine is fully open. Check that the inlet hose is not bent or kinked. Turn off the water, disconnect the hose from the machine, and clean the small filter screen inside the inlet valve.

Diagnose
U15
Dishwasher
General System & Mechanical Integration

Dishwasher does not fill with water.

Water supply issue. Water tap is closed, inlet hose is kinked, or the water pressure is too low.

Ensure the water tap is fully open. Straighten any kinks in the inlet hose. Check that the home's water pressure meets the dishwasher's requirements.
