Bosch Dishwasher Model SHU5316UC-06 -- what does error code 2H 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.

Test the water inlet electro valves.

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.

hold down scrub wash and the delicare or the 2nd one past scrub wash, for 3 seconds.

it sounds like your touch pad not the board

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.

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.
