Removed the front panel, then removed 2 screws to raise the top. Then turned the machine on to determine source of the leak. Removed the hose clamp on inlet, pulled off the hose and pulled out the injector valve. Reinstall of the new part took 5 minutes.
My first order was lost by fed-ex; appliance parts pros shipped a replacement order the day after I notified them of the loss! Customer service is outstanding!
