Clear the F144 error on a GE dishwasher with this troubleshooting guide

GE dishwashers use electronic controls to regulate wash cycles. The main control board coordinates with a variable-speed motor and inverter to clean dishes. When an F144 error code displays on the machine, it usually means the inverter needs servicing or replacement.

If you find out that you need any replacement parts for your GE dishwasher while you’re troubleshooting, you can enter your model number at AppliancePartsPros.com to order them. Most orders arrive in just two business days, and we have thousands of free guides to show you how to install your new parts.

Disclaimer: The error code information in this article is based on general service manuals and may not apply to your specific appliance model. While we strive to offer helpful advice for DIY appliance repairs, variations in models and configurations can lead to differences in troubleshooting steps, error codes and part replacements. For the most accurate guidance, we strongly recommend consulting the technical sheet for your specific appliance model.

What does the F144 error code mean?

On GE dishwashers with an electronic inverter, the F144 fault code typically means there’s an issue with the inverter.

The inverter provides variable voltage to control circulation pump speed during different parts of the wash cycle. By continuously adjusting motor speed, the inverter allows the dishwasher to use less energy without compromising thorough cleaning. Inverters can fail over time, and the F144 code is the dishwasher’s way of indicating that it may need to be replaced.

On models with an LCD, the F144 error will show on the screen. Units with LED indicators will usually flash the “Wash Temp Boost” light.

Potential causes of an F144 error code

Before you replace the inverter, it’s worth investigating a few common reasons why the F144 error would be displayed on the dishwasher.

• Loose wiring connections: Excess vibration can cause wires and contacts to loosen over time and become disconnected.
• Electrical supply issues: The inverter requires steady 120 VAC household electricity and 13.5 VDC from the control board. Any disruption can lead to the F144 code.
• Physical damage: If moisture enters the inverter casing or internal components overheat, that can permanently damage the inverter.
• Old age: Inverters are complex assemblies with a natural working lifespan. F144 faults and inverter replacements become more common as the dishwasher ages beyond 5-7 years.

Safety tips

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock.
• Turn off the water supply at the outlet before beginning repairs. Keep towels ready to catch any residual water in the system when removing parts.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.

How to troubleshoot the F144 error

Follow these steps to clear the F144 error code from your GE dishwasher.

Step 1: Access diagnostic mode

1. Enter diagnostic mode to verify the error code. On most models, you’ll need to press the “Cycle Select” and “Start” pads for 5 seconds with the door closed. Codes will display differently depending on the dishwasher. Units with an LED display will scroll F144 and other error codes. Models with indicator lights will flash the corresponding LED.
2. Make sure that the F144 code is present and record any other codes that you see.

Step 2: Inspect electrical connections

1. Unplug the dishwasher from the power outlet.
2. Check the harness plugs. Make sure the inverter wiring harness is firmly seated into mating connectors on the inverter housing. Reseat it if it’s loose.
3. Inspect the terminals. Look for corroded, burnt, or damaged terminals. Clean or replace them as needed.
4. Check the wire harness. All wires should be intact with no cracks or exposed conductors. If there’s any damage to the wires, replace the harness.

If all the connections look good, move on to the next step.

Step 3: Check voltage to the inverter

Once any wiring harness issues have been addressed, you can make sure the correct voltage is being supplied to the inverter.

LIVE VOLTAGE WARNING: For this test, the dishwasher needs to be plugged in and powered on. Please be very careful to protect yourself from electric shock, which has the potential to cause serious injuries. Don’t ever test live voltage if you’re uncomfortable using a multimeter.

1. Set a multimeter to VAC.
2. Use the multimeter probes to confirm 120 VAC at the dishwasher junction box.
3. Check for 120 VAC at connection J1109 from pin 2 to pin 3.
4. Set the multimeter to VDC.
5. On the main control board connector J1106, check for 5 VDC between pins 4 (white) and 8 (black).
6. Verify 5 VDC communication signals between the main board and the inverter.

If you get any readings outside the specified values and there’s 120 VAC reaching the dishwasher, replace the main control. If the main control voltages are good, replace the inverter.
