Samsung dishwasher troubleshooting
0E - Overflow error - Unplug the dishwasher from any electrical sources. If water still fills up, the inlet may need to be replaced. If the water stops when the power was unplugged, the main power board supply may need to be replaced.
4E – Water supply error - Make sure the water supply valve is open and unplug the dishwasher and shut the water supply valve off. Afterward, unplug the hose and inspect the inlet valve to ensure the screen is not clogged, and reattach it. Also, look at the wire connection to the water inlet valve and make sure the connections are tight. If the water valve does not open when started, then the water valve will need to be replaced.
4E1 – Water going in the dishwasher is above 175F degrees - Look at the temperature of the water heater. If it is above 120F degrees, lower the temperature. If the temperature is below 175F degrees, the thermistor also known as the temperature sensor could be faulty. In this case, the thermistor may need to be replaced. If this issue continues replacing the main power board assembly may help.
5E or 6E – Water drain error - Unplug the unit and remove any blockage from the drain sink, hose, and pump. Replace the hose or pump if cracked or broken.
9E – Low water - Remove any dishes that have collected water and restart the cycle. After the cycle has finished, make sure the dishwasher feet are level. Check the wires and reconnect any loose wires for the water sensor level. Also, replace the wire harness if broken. If the harness connections are good, then replacing the water sensor level may help.
bE2 – Jammed button on control panel - If a button is stuck, press all the buttons on the panel to try and remove the one that is stuck. If this does not work, then opting to replace the control panel could be an option.
HE – water heater - Unplug the unit and inspect the wiring connected to the heater. If the heater is broken, replace it. Also, if the heater is not working properly, then replacing the main power board assembly could help.
LE – Water leak - Check for any leaking water found under the unit. Also, inspect the drain pump, hoses, and tub. After finding where the leak is coming from replace what is causing the leak.
tE1 – Thermistor (temperature sensor) - First, unplug the unit and reconnect any wires from the thermistor wire harness that had come unplugged. Replace the harness if broken. If the wires are working properly, the problem may be the thermistor. In case the issue continues, replacing the main power board assembly is an option.
