Product Description

PRESSURE SENSOR ASM Specifications

This is a manufacturer-built pressure sensor for dishwashers. This pressure sensor, also known as a pressure switch, is designed to monitor the water pressure, communicate with the control board of the dishwasher, and accurately calculate the necessary amount of water for the washing cycle. If this pressure sensor is bad or not working properly, it will cause over and underfilling of your dishwasher, as well as excessive noise while in operation. To replace this pressure sensor, you will need a screwdriver and wrench to gain access and remove this part, and further disassembly of your dishwasher may be required. This sensor is sold individually and does not come with any other parts.

Sorry, we couldn't find any existing installation instruction that matched.
Dishwasher would not fill with water and would shut off
I found it online! There were step by step instructions that were easy to understand. I have never had to do anything like this in my life, only recently had to start doing everything around the house myself due to husband's illness.
The repairman came out, charged me $100 to determine what the dishwasher needed & left me with the part number. He was going to charge me $389 to install the part and they were over charging for the part. The repairman suggested I just get a new dishwasher.
I ordered the part from the website at 1/2 the price that the other place charges and found it on line. With the step by step instructions and the online page, I successfully installed it MYSELF. Saved me a ton of $$.
I LOVE the website
Thank You!!!!

Washer indicates FED code and quits. Will bad pressure switch cause this. I don’t see a float switch in this model. Drain hose is clear and hi looped. Thanks!!
For model number gdt530pgp5bb

Hi Coley, thank you for getting in touch. Based on our research, the FED code, or flood error detection code, indicates a high water level in the dishwasher. To solve this issue, you may first need to make sure the filter is clean. If that is not causing the issue, then the pressure sensor, part number PS12741258, is most likely faulty and may need to be replaced. We hope this helps!

Our dishwasher would not fill when we started it. I checked the fill valve and it is working fine. I was looking for the float switch and could not find one. I found the pressure switch. There are no error messages. I can get the dishwasher started if I would prime it by pouring water into the filter. Where did I look for the problem?
