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.

This error code means your booster heater is not getting up to the proper temperature. You can check your amp draw across your booster heating element to verify it is in fact heating and not blown. Also, check your temp sensor for resistance. At room temperature, you should read about 1000 Ohms. At 180 degrees, you will read about 1500 Ohms.
212 Boiler temperature too high Contactor faulty, probe faulty, check connection on XA5
The code 312 is the same as a code 212 as stated above.
There are dozens of error codes and you should be able to get them from your local meiko dealer, hope this helps, colin
111 Floor pan Leakage Leak inside machine activating ground float switch 302 At pumping out during rinse cycle level does not fall below level 1 Drain pump faulty, blocked, aqua stop not closing completely, no signal from circuit board (connection number 6 on XA1 connection plug)
Hi, i work on these machines on a regular basis and until very recently i was a Meiko service engineer- the code ERR203 means that there was no change detected at the boiler level switch during emptying- be it on the fill or rinse cycle.
This fault is mostly caused by the booster pump failing to pull water but could also be caused by blocked rinse jets or a faulty boiler level switch.
Hope this info is of use to you ,
