Maytag uses plastic nuts on the end of there dishwasher elements. The plastic housing of the nut also protects the heater elements wire.

To remove a Maytag style unit from under the cabinet, open the door and remove the screws that hold the unit’s mounting brackets to the counter. The mounting bracket prevents the dishwasher from falling forward when the racks are pulled out.

Most Maytag install crews will use stainless steel brained water lines, if your dishwasher is copper plumbed you will need to disconnect before the unit is removed.

Turning the power and water off before servicing  should be done first, with the water line disconnected pull the unit forward, you will need to access the rear of the unit.

Removing the heater wires, and twisting the plastic nuts off, this will loosen the heating element. Inside there are two metal brackets that hold the heater element to the tub, twisting the brackets will release the element from the insides.

The heating element should be tested with a volt meter, local appliance parts houses will often have volt meters for sale and can sometimes test the element for you. With the new element place in the dishwasher and secure using the two metal fasteners, from the back connect the heater locking nuts and hook the wires to the terminals.

Once the machine is installed fasten the mounting brackets back to the counter. Connection of the fill hose can be made with the dishwasher installed or pulled out depending on the dishwasher fill hose length. Purchasing longer fill lines and electrical connection will aid in an easier installation.

This is a very well known issue with Bosch dishwasher. Having repaired this issue myself over and over, I know this dishwasher and error well. Appliance repair companies have made thousands off just this repair alone.

Bosch dishwasher with the code 2H displayed in the digital read out will more than likely need the main control replaced #266746. The 2H means there is a heating issue, you need a multimeter to diagnose properly but here is a tale tale sign the board is bad.

Remove the dishwashers control panel, do so by removing the screws around the door, Bosch uses torq head screws on most of their appliances.

With the screws removed the control panel will release and fall forward, you will need to UN clip the control board from the plastic housing. On the bottom of the control there are several locking tabs, depressing them with a small screwdriver will release the board from the housing.

With the dishwasher control removed you can now open the plastic housing, the heater relay will be burnt, look for the missing or black solder mark on the board.

I have heard mixed reviews on soldering the control, sometimes it lasts most times it fails right away, I always replace the board its a sure fix.

Note also the thermostat located on the bottom side of the unit could also cause this error code, testing the thermostat with a volt meter should be done before purchasing any parts.
