Frigidaire Dishwasher Error Code i44

The i44 code means the pressure sensor signal has fallen below the acceptable range and stayed there for more than one second. The pressure sensor monitors water level inside the dishwasher tub, and when its signal is too low, the control board flags the fault and stops normal operation. This typically points to a wiring or connection problem between the sensor and the main control board, or a failed sensor.

It is not recommended to continue using the dishwasher while the i44 error is active. The control board relies on the pressure sensor to monitor water levels, and operating without a valid sensor signal could lead to improper fill levels or the wash pump running without adequate water. Address the fault before resuming normal use.

Repair costs depend on the root cause. If only the wire harness connector needs reseating or cleaning, there may be no parts cost at all. Replacing the pressure sensor typically costs between $20 and $60 for the part, while professional labor for diagnosis and repair can add $100 to $200 or more depending on your area. A main PCB replacement is the most expensive scenario, with parts and labor potentially ranging from $200 to $400 or higher.

Many cases of i44 can be resolved by a knowledgeable DIYer. Start by inspecting the pressure sensor wire harness and its connectors at both the sensor and PCB ends for looseness, corrosion, or visible damage. If the connectors are secure and the wiring looks intact, testing and replacing the pressure sensor may require a basic multimeter and some comfort working inside the dishwasher. If the main PCB is suspected, professional diagnosis is recommended.

A reset may temporarily clear the i44 code, but it will return if the underlying cause has not been corrected. Because the fault requires the signal to be out of range for more than one second, a persistent wiring fault or failed sensor will trigger the code again as soon as the dishwasher attempts to operate. Resetting is useful for confirming the fault is repeatable, but it is not a repair.
