Fault Cause: Aging wire insulation, moisture, poor contact, motor failure

Solution:

• Cut off power immediately to avoid electric shock hazard
• Professional detection of leakage points and replacement of aging wires
• Check motor insulation performance, replace motor if necessary
• Install leakage protection device to improve safety

Fault Cause: Circuit overload, short circuit, leakage, protection switch failure

Solution:

• Check circuit load, avoid using too many high-power devices at the same time
• Troubleshoot short circuit points and repair circuit faults
• Detect leakage and solve leakage problems
• Replace faulty protection switch to ensure normal protection function

Fault Cause: Loose power plug, blown fuse, damaged power cord, control board failure

Solution:

• Check if the power plug is firmly inserted, replace socket for testing
• Check fuse and replace blown fuse
• Check if power cord is damaged, replace damaged power cord
• Detect control board, repair or replace faulty control board

Fault Cause: Control system failure, sensor failure, motor failure, poor line contact

Solution:

• Restart the equipment and try to resume normal operation
• Check control system, upgrade or repair control program
• Replace faulty sensor to ensure normal signal transmission
• Inspect motor and lines to solve poor contact problems

Fault Cause: Poor button contact, damp button panel, control board failure

Solution:

• Clean the button panel to remove dust and oil
• Check button contacts and repair poor contact issues
• Dry the damp button panel to prevent short circuit
• Detect control board, repair or replace faulty control board

Fault Cause: Clogged drain pipe, water pump failure, drain valve failure, water level sensor failure

Solution:

• Unclog the drain pipe and remove blockages
• Check water pump operation status, repair or replace faulty water pump
• Check drain valve to ensure normal opening and closing
• Calibrate or replace water level sensor to ensure normal drainage signal

Replacement Reason: Water pump burnout, water leakage, abnormal operation, insufficient flow

Replacement Process:

• Cut off power and water supply to ensure operation safety
• Remove old water pump and clean installation position
• Install new high-quality water pump, ensure firm installation
• Connect pipelines and lines, test operation status
• Adjust water pump pressure and flow to meet usage requirements

Fault Cause: Motor burnout, transmission mechanism jamming, power failure, control system failure

Solution:

• Check if the motor is powered on, eliminate power failure
• Check transmission mechanism, remove jamming objects, add lubricating oil
• Detect motor windings, repair or replace burned motor
• Check control system, repair faulty control signals

Fault Cause: Water pump failure, water circuit blockage, insufficient water level, control valve failure

Solution:

• Check water level and add sufficient water
• Unclog water circuit and remove blockages
• Check water pump operation status, repair or replace faulty water pump
• Check control valve to ensure normal opening and closing

Fault Cause: Motor burnout, power failure, damaged start capacitor, line break

Solution:

• Check power supply to ensure normal voltage
• Check start capacitor and replace damaged capacitor
• Check motor lines and repair line break issues
• Detect motor windings, repair or replace burned motor

Fault Cause: Clogged oil filter, blocked exhaust pipe, insufficient motor speed, excessive oil accumulation on wind wheel

Solution:

• Remove oil filter and thoroughly clean blockages
• Unclog exhaust pipe and remove oil deposits in the pipe
• Check motor speed, adjust or repair motor
• Clean wind wheel, remove accumulated oil, restore exhaust efficiency
