Ryobi Ryobi RY142300 2300 PSI Brushless Electric Pressure Washer THERMAL RELIEF Error Fix: Hot Water Discharge From Thermal Relief Valve

Water is dripping or flowing from a small valve on the pump (the thermal relief valve). This is actually a safety feature functioning correctly. When the pressure washer motor is running but the spray gun trigger is not pulled, the pump recirculates water internally through the unloader valve. Recirculating water heats up from the friction of being continuously pumped. After approximately 2-3 minutes of running without trigger use, the water temperature can exceed 140°F (60°C), which can damage the pump seals. The thermal relief valve opens to release this overheated water and allow cooler supply water to enter the pump. To prevent thermal relief valve activation: do not let the pressure washer run for more than 2 minutes without pulling the trigger. If you need to take a break, turn off the motor. The thermal relief valve is NOT a malfunction — it is protecting the pump from heat damage.
