To Next PageTo Next PageWhat to do if my EMP WP120 12V is running but not pumping fluid?
If your EMP Water Pump is running but not pumping fluid, you should first check the system fluid level. Also, inspect the tubing for any restrictions, such as kinks. Make sure the pump is primed, and check for a collapsed inlet or outlet hose. Finally, check the pump inlet for any trapped debris that may be obstructing the flow.
Why is my EMP WP120 12V Water Pump not running?
If the EMP Water Pump isn't running, start by checking the electrical connections. Next, check the ignition enable wire and ensure it is 'on'. Also, verify the correct location of the ignition enable pin.
How to fix excessive noise from EMP WP120 12V?
If your EMP Water Pump is producing excessive noise, begin by checking for cavitation or low inlet pressure. Inspect the pump inlet for trapped debris. Examine the plumbing around the pump for valves or components where cavitation may be occurring. Also, check for a collapsed inlet hose.
What to do if EMP Water Pump has a seal leak?
If there's a water pump seal leak in your EMP Water Pump, first verify the coolant level. Also, verify the coolant selection; for water seal life, OAT, phosphate-free, silicate-free coolant is recommended. Sample the coolant and review coolant maintenance records. Verify the system is not aerated. Finally, check for cavitation or low inlet pressure.
How to troubleshoot CAN communication issues with EMP WP120 12V Water Pump?
If your EMP Water Pump has no CAN communication or isn't responding to CAN commands, check the communication harness wiring. Verify that CAN messages are being transmitted in the proper formats and that the proper component CAN address is being used.
