What you need to do is check the resistance of the booster tank temperature probe. The error 210 means a short circuit in the booster temp probe. At room temperature, the resistence should read about 1k Ohms. If you are reading significantly lower than that, then you will need to replace your booster temperature sensor. You also want to check the 4 pin square molex connector on the I/O board on top. Make sure all connections are tight, secure, and that there are no "bridges" across the connections for the temp sensors.

We have a model FV 40.2 in our office. We have had a repairmen here three times and the dishes don't get clean. Dirt collects on top of the strainer at the bottom of the unit and cakes on to the dishes and the racks. How can we fix this?
