Have this dishwasher in one of the rental units,and it is taking a very long time to complete the wash process.It seems like it used to take about an hour and a half to complete the cycle,but now the tenant says sometimes about 3 hours.The tech sheet is missing so I need help in troubleshooting this thing.I have checked the hot water and if you let the kitchen sink faucet run before starting dishwasher it gets to 118 degrees.Can you provide a tech sheet and help me along?
