Fault 51 - Brother MFC 240C All-In-One InkJet Printer

The most common reason for this code is :-

F51 error is caused by a faulty or blocked heater pressure switch. It is not a job for an unqualified person.

"The program is interrupted and the drain pump is operated. The display shows Technical fault F51. Call Service Department. The buzzer is activated for 2 minutes. "

if you have a 51 fault the machine must be a diverter valve model machine which has a water save function,check the diverter has nothing jammed in it and that the soleniod is ok with a multi meter if it passes both checks then it your main computer board

That flashing indicates fault code 51. Fault code 51 indicates a problem with the driver's seat belt circuit. The seat belt buckle has a switch in it to determine if the belt is buckled up when the seat is occupied [determined by a pressure sensor in the seat bottom]. The switch in the buckle is either bad or the wiring to the switch is either short or open circuited.
Use of a computer scan tool can help narrow down the problem. There are four different scan tool fault codes relating to code 51. They are B2432, B2433, B2434 & B2435. These codes will give you more defined information on the actual fault. Most common faults are either a bad switch in the seat belt buckle or damaged wiring to that switch. Damaged wiring is usually caused by the driver placing objects under the driver's seat, which damage the wiring coming out of the seat belt. It is also possible to have a bad seat belt computer [Restraints Control Module or RCM]. A bad RCM is not common. Check for damage to the seat belt wiring under the driver's seat. Best to remove the seat and lift up the carpeting to do this. If no physical damage or water corrosion damage is present, replace the seat belt. After repairs, disconnect the battery for 1 minute to clear the fault code from the RCM's memory.

This is error code 51
51. (00110011) Phase 5 and 6 Eco - Diverter Valve Fault
Primary: The motor controller has registered a drop in water level in the
recirculation phase of the wash cycle, water is being drained instead of recirculated.
Or water has been sprayed onto the Valve from an external source and caused the
solenoid to blow.
Action:
Turn the power off at the machine but leave the power on at the wall, then measure
the voltage across the terminals of the wax actuator, if a reading of 230V is
achieved the motor controller has failed due to the valve and both will need to be
replaced.
Secondary: Check for blockage in the valve itself or a broken hinge mechanism.

Hi there:This is a CHASSIS fault code... DTC C1201/51 - Engine Control System Malfunction.

Possible that the fault relates to the weakness/absence of the G- signal process in the RGB network. It can be related to many issues, the failure of the IC, dry soldering of the IC or related circuit or failure of passive compoents here.
Need a check with a schematic to find the fault.

the ECM has sensed a fault in the Prom

Common fault on FORD

Usually due to a poor connection in the YELLOW PLASTIC CONNECTOR underneath the passenger seat.

Just push it together properly and it should clear the AirBag fault

Our washer did the same but it was after I took the excess drain hose and pushed it into the drain in the wall. I thought it looked "more tidy" In doing so I created a siphon effect. Once I pulled the excess hose back out it was fine.
