Error code 2H.....or stops on last minute

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

Hello, welcome to FixYa.

The dishwasher you're speaking of (provided it is indeed a Gaggenau GM954) is built by Bosch as you may or may not know.

To address your concern regarding the 2H in the display actually needs to be done in two parts. I'll start with the basic info associated with the 2H displayed.

This can be simply indicating the previous cycle exceeded a 2 hour wash cycle, not necessarily an error and can be attributed with too cold water entering the dishwasher (below the recommended 120F), a longer than normal drain time (due to partial blockages, kink etc. hence longer time needed to complete the cycle) or inproper water circulation during the cycle.

Aside from these issues, it (2H) can also mean the unit has a heating error and if left long enough will show another error of "1" in the display, extremely long wash times, etc.

**The first thing I'd suggest before attempting any repair is running an additional cycle while making sure the water inlet is hot (120F optimum) and the unit does indeed drain fine.

**A fair indication of proper draining is to start a cycle and once washing begins (2-3 minutes) activate the "cancel" and the unit should adequately drain in the 2 minute time allowance.

**To identify proper water circulation, place an empty cup in the upright position in the top rack, start a cycle and inspect the cup after 2-3 minutes and it should be full of water.

After trying and posting the results of these thing's we can move forward with potential heating errors, the cause, and how to remedy them. Let me know what you find and I'll continue to assist you in any manner possible going forward. Good luck.

This happens to Bosch dishwashers because the dishwasher stops heating the water and the dishwasher keeps running trying to heat the water up. Go to the link below and it will explain how to fix the issue.

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.

The "2H" is an error code indicating the control panel needs to be replaced.

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.
