Wireless Control Module Troubleshooting. The RED FAULT light means there is likely a short in the cable feeding to the module. Please check all your connections, especially for proper grounding. The BLUE fault light means there is “over amperage”, bu

Please back off the unloader valve by turning the knob counter- clockwise before switching on the pressure washer, and then gradually turn the knob clockwise to build pressure. Failure to do so could trip the circuit breaker. It would also reduce motor life considerably.&#xA0;&#xA0;<p style="margin: 0px 0px 10.6667px; padding: 0px; font-weight: normal; font-style: normal; vertical-align: baseline; background-color: transparent; color: windowtext; text-align: justify; text-indent: 0px;"><span style="margin: 0px; padding: 0px; font-size: 16px; line-height: 25.575px; font-family: &quot;Barlow Condensed&quot;, &quot;Barlow Condensed_EmbeddedFont&quot;, &quot;Barlow Condensed_MSFontService&quot;, sans-serif;">If the breaker trips before the unloader valve knob reaches the&#xA0;maximum&#xA0;limit, please stop turning the knob. Turn the unloader knob counter- clockwise a little and mark that spot as the max operating condition.&#xA0;<p style="margin: 0px 0px 10.6667px; padding: 0px; font-weight: normal; font-style: normal; vertical-align: baseline; background-color: transparent; color: windowtext; text-align: justify; text-indent: 0px;"><span style="margin: 0px; padding: 0px; font-size: 16px; line-height: 25.575px; font-family: &quot;Barlow Condensed&quot;, &quot;Barlow Condensed_EmbeddedFont&quot;, &quot;Barlow Condensed_MSFontService&quot;, sans-serif;">To rule out&#xA0;issues&#xA0;with the module, please plug the&#xA0;motor&#xA0;directly to the power source instead of the wireless module, and see if the machine works okay like that without tripping the breaker. If it works fine,&#xA0;then there is an issue with the module itself.&#xA0;<p style="margin: 0px 0px 10.6667px; padding: 0px; font-weight: normal; font-style: normal; vertical-align: baseline; background-color: transparent; color: windowtext; text-align: justify; text-indent: 0px;"><span style="margin: 0px; padding: 0px; font-size: 16px; line-height: 25.575px; font-family: &quot;Barlow Condensed&quot;, &quot;Barlow Condensed_EmbeddedFont&quot;, &quot;Barlow Condensed_MSFontService&quot;, sans-serif;">If the module is fine, then first look for a clog somewhere in the system. Please visually check the gun,&#xA0;hose,&#xA0;and unloader valve. You may have to take the unloader off the pump to visually inspect it.&#xA0;If the issue is an internal&#xA0;component&#xA0;of the unloader, you will not see anything.&#xA0;<p style="margin: 0px 0px 10.6667px; padding: 0px; font-weight: normal; font-style: normal; vertical-align: baseline; background-color: transparent; color: windowtext; text-align: justify; text-indent: 0px;"><span style="margin: 0px; padding: 0px; font-size: 16px; line-height: 25.575px; font-family: &quot;Barlow Condensed&quot;, &quot;Barlow Condensed_EmbeddedFont&quot;, &quot;Barlow Condensed_MSFontService&quot;, sans-serif;">Please plug the motor back into the module.&#xA0;<ol style="list-style-type: decimal;margin-left: 0px;"><li style="margin-left: 24px; font-size: 16px; text-align: justify;"><span data-contrast="auto" lang="EN-US" class="TextRun SCXW94711741 BCX8" style="margin: 0px; padding: 0px; line-height: 25.575px; font-family: &quot;Barlow Condensed&quot;, &quot;Barlow Condensed_EmbeddedFont&quot;, &quot;Barlow Condensed_MSFontService&quot;, sans-serif; font-weight: bold;">Run the machine without a nozzle at the tip of the gun.
