I have a MEIKO sanitizer model FV 40.2. that doesn't seem to shut down properly. After shut down the lights all come on again.

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.

SOURCE: gets to 35-40 degrees then doesn`t maintain

This can be caused by the drain hole below freezer coil being blocked by ice. You MUST remove all ice in drain under freezer coil. Use turkey baster to squirt hot water into hole and use hairdryer to defrost. Possible defrost thermostat is defective. Unit never goes into defrost, ice forms on coil and in floor of freezer. After defrosting may work OK for a week or two but gradually gets warmer because ice is blocking ports where cool air gets to refrig. May also have water in refrig box. Can also be caused by defective defrost timer.

This is a long shot... been many years. I have an SHU33 dishwasher with same exact thing happening. Did you ever find out what was going on?
