What is error 1 message mean?

I couldn’t find any error code 2H but I did find an error code H2O. This code means insufficient water pressure. If the display reads 2H, it usually means the start delay function is turned on. The dishwasher will turn on in 2 hours if door is closed. This dishwasher is advanced. To understand all operations you should read the user guide or manual.

turn off the water and remove the hose at the rear of the machine. Inside you will find a small wire gauze strainer. This blocks with limescale and debris from the water mains, just enough to reduce water flow below the thresholds..

E1 F8 Whirlpool dishwasher If F8 E1 or LF (too long to fill) appears in display, it means the washer is taking too long to fill. It's possible the drain hose extends more than 4.5" (114 mm) into standpipe.

F8 E1 Error Code for Top Load Washer - Product Help

What do you mean, it won't "run past the wash cycle"? Do you mean it stays in the wash cycle forever? Or do you mean it quits in the wash cycle and doesn't rinse or dry?

The SHU4326 and 4326 models use "Regular Wash" and "Rinse Hold" to begin the test while the other three series in this section use "Scrub Wash" and "Delicate/Econo," but all use the same set of fault codes, shown not as lights but as numbers on the Cycle Countdown display. Here, 1 is an aqua sensor fault, 2 is a heating fault, 4 is a filling fault, 8 is an NTC fault and 0 means that everything is working as it ought. During an actual wash, when you aren't testing, the Cycle Countdown display may show the letter "F," which also signifies a filling fault.

Do you own an LG LDF6810ST dishwasher? If not, please reply with the manufacturer name, model and serial number.
Are you saying that the display that normally shows the time is displaying an code of 2H? On an LG, that means 2 Hours, (120 minutes) and is not an error code.
On an LG with a symptom like this, I would arrage to replace the main processor card (PCB). You would be getting an error message if the motor (wash or drain) had failed.

Because you are not getting an error message, I agree that the controller card is malfunctioning. Almost everthing else would triger an error.
Recommend replacing the controller card.

Hi, i work on these machines on a regular basis and until very recently i was a Meiko service engineer- the code ERR203 means that there was no change detected at the boiler level switch during emptying- be it on the fill or rinse cycle. This fault is mostly caused by the booster pump failing to pull water but could also be caused by blocked rinse jets or a faulty boiler level switch. Hope this info is of use to you , Kitcheneer
