My maytag commercial washer display a code F26

SOURCE: Maytag front loader washer--door won't open but lock light off

Open the soap dispenser. Look down in front of the fabric softener dish.
You should see a yellowy-green plastic cord (like weed-whacker line). Pull it.
The door should open.

If you don't see the cord, remove the four screws that hold the dispenser lid in place to find it. Just don't lose it when you put the cover back on.

it is a problem with the motor .this is confirmed.

Issue Washer stops in mid-cycle and/or flashes a code.
Warranty Standard product manufacturing warranty applies.
Action The motor drive system experienced a momentary loss of neutral feed from the power cord to the
Motor Control Board. The neutral line for the Motor Control Board passes across the water valve
solenoids. Neutral to the motor drive system can be momentarily lost If there is poor crimping of any
of the wire terminals in this circuit. This situation could result in a misdiagnosis and unnecessary
replacement of the Motor or Motor Controller Board.
Current Neptune front load washers will indicate a false locked rotor signal to the Machine Control
Board. Washers with a LED display will flash code “LR” in the display. LCD washers will display
“Locked Rotor.” The earlier built front loaders will not display a code, but simply shut down in midcycle
or will not start.
Pull each terminal of the white wire harness connected to each water valve solenoid and verify the
wire is properly stripped and crimped to the metal terminal connector of the wire harness. Make sure
the wires fit snug on the terminals of the water valve solenoids.
A product improvement has been made to the following models. The neutral wire is routed across
the pump only, and now by passes the water valve solenoids.

LE means "Overload in Motor" Unplug the washer, remove clothes, wait 15 minutes for motor to cool down. try again. If problem persists you'll need a certified technician.

Try these steps:

1.) Take the washer outside. 2.) Loosen the two screws on the back panel and remove the back panel. The pump sits on the left-side of the opening. There's a black water hose with a metal clamp; 3.) squeeze the metal clamp with your fingers until it's loose enough to slide away from the pump. 4.) Separate the hose from pump and the trapped water will pour out and the door will then open; and 5.) clear any blockage from the drain hose and the pump.
