I had just finished my route- and was on my way back to the office, when I decided to pull in to a Seven Eleven to enjoy an ice-cold beverage on a hot summer day. As I was slurping on the empty cup like a kid, my phone rang. It was my boss on the other end advising me of an emergency service call not too far away.
I quickly jotted down the customer’s address along with the appliance information. this included the model (WFW9400) number of the appliance.
Whirlpool duet front load washer
The product was a whirlpool duet washer that was leaking from the front. I approached the washer, check the power supply and ran a diagnostic test c07 (drain pump), c00 (door lock) and c03 (dispensing system). The result of the diagnostic test came back positive. The machine was functioning as it should. I put the washer on a quick wash cycle as I looked inside the washer, I noticed this.
The excess suds tells me, that the customer had added too much detergent therefore causing excess suds to leak through the door of the washer. The other cause of the leak could also be a faulty drain pump. Remember I said the diagnostic test yielded nothing. What is wrong with this washer? I asked myself. Where was the leak coming from? I didn’t for one second thought the customer was crazy. I was determined to find this leak.
I tipped the washer backwards and removed the lower plate. The tool required for this task, is a 1/4 inch (3 screws) nut driver. The drain pump will be smack in front of you and will be held in place with a phillips head screw. I removed the screw and dislodge the pump from it’s housing. Slowly and with caution, I unscrew the drain pump cap, as there will be excess water inside the pump that will leak on the floor.

A good service technician should be well equipped with a wet-vac for situations like this. So, I vacuum the the drain pump, found and removed debris that had gotten in the drain pump. Luckily for the customer, the debris did not cause any damage to the drain pump impeller, which could have resulted in a costly repair for my customer.
I carefully put the washer back to it’s original state and informed the customer of my findings.
Whirlpool duet front load washers are in the HE (high efficiency) category, which means only a small amount of detergent is required. If too much detergent is used, the washer sensors will activate and will sometimes generate an error code. too much detergent = suds leaking through the door.
