That would be fuel warning and fuel Sensor out of range. Both the same problem. Likely bad fuel lever sender in tank
Codes are as follows
ECL engine coolant level
EC engine coolant temp
EP engine oil pressure
ES engine speed
AF air filter
H Hydrostatic fluid temp
b Battery (show on display in Lower Case)
FUEL fuel level
HF Hydraulic Filter
HP Hydraulic Fluid pressure
All these codes will be followed by a number, not all numbers apply to all codes
Example 1 is the engine shutdown code but there is no FUEL 1 or No AF1 because these are not serious failures.
Numbers are as follows
1 Shutdown engine in 30 seconds
2 Warning
3 wire not conected
4 wire shorted
5 High sensor voltage
6 Sensor no signal
7 Sensor out of range
If you see some sort of jiberish on the display you likely have a bad ground .
There are also code number 1.1 2.1 and 2.2
EC has a 1.1 shutdown and a 2.1 Warning code
ES hase a 2.1 warning code
b has a 2.1 warning bad battery and a 2.2 Warning battery voltaage
