Have problem with ipso 35 commercial wash .washes ok but when goes into drain and spin timer stays on one minute but doesn't drain or spin

If it actually goes on and finishes the cycle and that really bothers you replace it. If not leave it alone and allow a little more time to complete its cycle. The lid switch only keeps the spin cycle from going with the top open.

Check if drain filter is clear and drain pump is working properly. Also remove soap conditioner tray and check if you have black residue inside the soap/conditioner dispenser. Sometimes this can prevent water from entering the conditioner tray.

It could be the timer or circuit board, until it is not draining, will not spin
If the timer or circuit board is OK, the you have a faulty drain pump or motor, to check this out remove the back panel.

see the next steps and use the common sense: God bless you
When the cycle doesn't advance, it's probably the timer or a cold-water supply problem: It's the timer, if your washing machine fills with water and begins agitating, but the timer never advances--or if the washer is in a spin cycle and the timer won't advance. Then you need to replace the timer. It may be a cold-water supply problem, if the washing machine fills with water, agitates, drains, and spins, but then doesn't fill with rinse water. See There's no cold water.

the belt has come off or broken on the back take lid or back panel off and have a look

If the timer gets to the rinse cycle and stops,
Check the lid switch for continuity. If no continuity replace the lid switch.
If the timer continues through rinse and spin without doing either, replace the timer.

Timer is defective. Your unit has a netural drain. When finished agitating, the shuts down and then starts up reversing to drain and spin. On the initial reverse start, the water drains without the transmission spinning. After a timed period 3-4 minutes, the timer is supposed to pause, stopping the motor for a few seconds. When the motor stops again, the transmission shift to the spin cycle and when the timer resumes power tothe motor it should spin. You are doing the same thing when you lift the lid...stopping the timer and then the tranny shifts and when you set the lid down, the washer spins. Replace the timer.......
