My digiweigh scale reads HHH What does this mean and how do fix it

Generally, an HHH error code means the machine is sitll too hot from making the previous loaf. Keep the door open for a bit and allow it to cool down.

If the receiver and/or the transmitter display LLL or HHH instead of the probe temperature,
wait for probe to reach room temperature. If LLL or HHH is still displayed it is likely the
internal probe wire has shorted out either through moisture or heat damage.

This means that the read is over the HIGH limit of the sensor, perhaps is too hot there. Change it to another location. josemaX
