Help-Water Softener Error 3 Whirlpool WHES40


New member
Hi everyone, I am on a tight budget and my water softener broke down. It's a Whirlpool WHES 40 with an error message 3 and Service message. I followed the manual and cleaned the venturi, and all that section that the manual calls. I plugged back in and the same error code.

The switch appears to open and close, the sprocket or top gear rotates, I can hear a noise as if water is entering but I am not able to see if water is actually entering. The water softener seems to cycle thorugh, but the message is there. Before ordering the seal package #18 that costs $43.00, and the switch, Is there anything else that I need to clean to rule out as the cause?

Thank you in advance for your help.
