WashR DUO | For the TSS Version only. The motor starts even with gun trigger is released

If your WashR DUO features the Total Stop System (TSS) and the motor continues to run even when the spray gun trigger is not pulled, it usually points to an issue in the high-pressure system. This behaviour isn't normal and should be addressed to prevent long-term wear on the pump.

Common Causes & Fixes

Possible Cause What You Can Do
Nozzle is clogged Remove the nozzle and inspect it for blockages. Clean thoroughly and reinstall.
High-pressure system or pump circuit is not watertight There may be an internal leak or faulty seal. Submit a warranty claim or order the required replacement part.
