Dishwasher error code 2h - Siemens 24 in. SE25T250 Free-Standing Dishwasher

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.

It not an error it sound like it on a delay of 2 hours

2H is not exactly an "error code", but it does indicate a problem. It means that the machine exceded its wash time by more than 2 hours. This is usualy caused by a failure of the heater, most often caused by a failure of the controll. Remove the control from the door, remove the plastic housing from the control, and check for a bad solder joint on the heater relay.
If you find a bad solder joint, REPLACE the controll.
Or call a qualified service person.

NOTE: The SHU53A dish washer with serial numbers from FD8205 to FD8507 are included in a factory recall. If your dishwasher is one of these contact BSH @ 1-800-586-9226 24/7.

My Bosch dishwasher did the same thing. When the wash cycle starts, the dishwasher fills with water and then the heater is supposed to turn on to heat the water. If the water does not heat, then it will display 2H continuously. The heating element may be bad, but a more likely cause is with the control module. Bosch has a problem with the control module printed circuit (pc) board that powers the heater on many models. The solution requires some technical expertise and soldering skills. The details are explained in the document "Bosch dishwasher troubleshooting tips" on page 11. Download here
Bosch recommends re-soldering the connection, which is a temporary fix. The problem is that the copper conductor (called a trace) on the circuit board is not wide enough to handle the current required for the heating element, and as a result the copper trace overheats, causing the solder to melt on the relay connection. The best solution is to remove the control module PC board and solder a short length of copper wire between the pins to prevent the overheating problem, as shown in the attached photo (magnified portion of PC board). I did this on my dishwasher and it has been trouble-free for over 3 years.

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.

I would check the buttons on the control they may stuck. check the delay button..

The control panel needs to be replaced (indicated by the "2H" error code displayed at the start of the cycle).
BTW - The number 1 displayed at the end of the cycle indicates the cycle has timed out (i.e., it doesn't mean 1 minute remaining). Hence the continued running of the unit. Until you replace the control panel, you'll have to manually cancel the cycle at this point.

I had the same problem and just today replaced the control board module. Purchased the control module online and installed in myself. Was not that difficult. undo the screws (torx screw driver needed) unhook the connections to the board and label all. Pull the board out and open, found burned connectors. Now works like a dream.

I don't think you'll find it's the control board.
I think you'll find it's the heater box.
Not an easy job to do yourself unless of course you know what you are doing.
I would suggest you contact Bosch. One other possiblity is that the water inlet is blocked, although to be honest this is very rare.
