Tank Full " TF" is not a fault, it is a status indication in drive, which is arrived form the liquid probe, if installed.
If the customer is not using using liquid probe(water level sensor), they should change the parameter "LPA" to "NO". As default this parameter setting in drive is AI2, hence it should be changed to "NO" to avoid Tank Full "TF" indication. Refer the screen shot below for the parameter details.
