Minimax nt tsi 400 power

Have the older Minimax nt tsi 400.   Went out to check the equipment and the only light that was on was the "Pressure SW" light.  Had a good electrical storm go through and take out my WiFi router, electric dryer and I guess the pool heater.  I replaced the transformer, hoping for a cheap fix but it did not work.     What do you think is bad....the main digital display #472100?  Thanks

Try and jumper the pressure switch and see if anything changes. Remove the 2 wires from the switch and join them together with a paper clip or interlocking them together. This will bypass the pressure switch. Had one storm few years back that took out 3 spas in one night. Just dead.. tried everything buy it likely wipes the chip
