Electrical Repair On A Nilfisk DTE Wallmount Unit In Bardon

What they needed

We were called out to repair a wall-mounted Nilfisk DTE static pressure washer that had completely stopped running. The machine is used regularly for cleaning duties on site, so a quick diagnosis and repair was needed to get the unit operational again.

Problem / Requirement

• Machine type: Nilfisk DTE wall-mounted static pressure washer.
• Issue: The machine would not start or run at all.
• Diagnosis: The electrical contactor had burnt out, preventing power from reaching the motor.
• Additional fault: The overload protection had also failed due to the electrical failure.

Without a functioning contactor and overload, the motor could not safely start or run.

Our Solution

• Removed the failed electrical contactor from the control panel.
• Replaced the burnt-out contactor with a new unit.
• Installed a new overload to ensure proper motor protection.
• Checked electrical connections and tested the system to confirm correct operation

The Result

• The Nilfisk DTE wall-mounted pressure washer was quickly returned to full working order.
• With a new contactor and overload fitted, the machine now starts reliably and operates safely.
• A straightforward electrical repair that got the customer back up and running with minimal downtime.
