Manager said both fryers don't fill all the way and the filter times are wrong. Removed filter pipe clean out plug. It was clogged. Cleaned and reinstalled. Did a filter cycle on both fryers. Drained ok. Oil returning is strong. Pump/motor sounds normal. No strange noises. Oil returned normally. Did the Oil Quality check ok. Heated back to set temps. The filter times are off because the time is not set correctly. It was off by 4 hours. Reset time in settings. Time now set correctly. Back in service.
