Westinghouse ePX3500 Electric High Voltage Cleaning Machine

Leakage at the connection point: 1. Damaged or missing sealing ring; 2. The joint is not tightened; 3. Damaged hose: 1. Replace the sealing ring with the corresponding specification; 2. Tighten the joint clockwise (do not apply excessive force); 3. Damaged hoses need to be replaced immediately

The machine will automatically stop after running for 2 seconds. The automatic start stop function is normal (if the trigger is not pressed, the pump will stop after the priming is completed). Pressing the trigger of the spray gun can start it without maintenance; If the machine stops frequently after pressing the trigger, check if the nozzle is blocked or if the pipeline is stuck

The trigger cannot be locked, and the safety lock is stuck or damaged. Check if there are impurities stuck in the safety lock, rinse with clean water, and try to operate it; If it still cannot be locked, the trigger assembly of the spray gun needs to be replaced

GFCI plug frequently trips 1. Circuit leakage; 2. The specifications of the extension cable do not match; 3. Internal electrical failure of the machine: 1. Stop using and check if the plug and cable are damaged; 2. Replace the extension cable that meets the requirements; 3. If it still trips, contact after-sales maintenance for repair

Maintenance and Storage

1. Daily maintenance

After each use: empty the soap box, inject clean water and rinse the pipeline through the soap nozzle; Clean the nozzle (use specialized tools or fine needles to remove blockages); Clean the inlet filter screen.

Regular maintenance: monthly testing of GFCI leakage protection; Regularly inspect high-pressure hoses and sealing rings (lubricated with non water soluble grease), and replace hoses immediately if they are damaged (non repairable).

2. Storage requirements

Environmental conditions: Store in a dry, heated indoor environment with a temperature not lower than 4.5 ℃ (to prevent the pump body from freezing and cracking), away from flammable materials and high temperature sources.

Preparation before storage: Disconnect all pipelines and drain any residual water from the pump body; Disassemble the nozzle and spray gun, clean and store them; Use pump body protector (optional) to extend the lifespan.

Common troubleshooting

Possible causes and solutions for the fault phenomenon

After starting up, there is no water flow. The water source is not turned on, the inlet filter is blocked, the hose is bent to open the water source, the filter is cleaned, and the hose is straightened

Insufficient pressure/intermittent discharge nozzle blockage, insufficient water source pressure to clean nozzle, replacement of qualified water source

The sealing ring at the connection is damaged/missing due to water leakage, the thread is not tightened, replace the sealing ring, and tighten the connection again

The automatic start stop function of the machine stops after running for 2 seconds (without pressing the trigger) and can be started by pressing the trigger, no maintenance is required

GFCI plug cannot reset due to circuit leakage, plug damage and stop using. Contact after-sales service to replace the plug

The spray gun cannot lock the trigger and the safety lock is faulty. Check if the safety lock is stuck and if it is damaged, it needs to be replaced
