49.xxxx error is a catch all. Could be bad firmware, bad network, bad print job, etc.
Power off your PC. Power off the printer. Power on the printer then the PC. Do you have the 49 error now? If not print something, but not what you printed when you got the error. If you are still good, try printing something else. Still good, the error probably went away. If it errors again, somebody will have to look at it. Maybe upgrade the firmware or replace the formatter. How old is the printer? Is it still on warranty?
The most common problem with AquaSmart is the pump
not the water valves
The pump has gone bad and blown some parts in the motor controller board and the fuse to the water valves.
Some AquaSmart machines display the wrong Error code (49)
witch is not the correct code for this problem.
Pump and motor controller board need replacing.
Maybe cheaper to buy a good secondhand machine.
Thank you for the inquiry.
It would be helpful to know which printer this is, when the error occurs, and how old the printer is.
I suspect this is a HP LazerJet and possibly a firmware issue. If it's still under warrenty HP Support will walk you through the steps to upgrade the firmware.
Before contacting your dealer make sure it is not a document you are trying to
print which is causing the error. The 49 error is a firmware error and most of
the time it is because a document confuses the printer either with its coding or
composition. Sometimes just updating the firmware on your printer will fix it.
Sometimes copying the ofending file to another file and printing the new file
will solve the issue. Clear out the print que so nothing is being sent to the
printer. Now reactivate the network card and first try with a simple test page
and work from there.

the code error (49) is telling you that the inlet valve is not working make sure the hoses are not blocked. if you have fitted the valve and is still not working then i would try using the unit on cold if it still does not work then there must be a short in the p.c.b control board.
49 errors are possibly one of the most difficult to diagnose.
49 Indicates that a firmware error occurred that caused the processor on the formatter to abort an operation. This type of error can be caused by invalid print commands, corrupt data, or invalid operations. In some cases, electrical noise in the cable can corrupt data during transmission to the printer. Other causes include poor quality parallel cables, poor connections, or home-grown applications. On some occasions, the formatter is at fault, but this is usually indicated by a 79 Service Error.
I see you state a 49FFF? any other letters or digits displayed? Specifically 49 FFFF can be a problem if the ribbon cable from the DC controller to the interconnector board is not connected. The control panel display will also be dark.
Other 49 FFx errors can be:
NEC firmware chip error - replace the Firmware Unsupported EDO Memory installed - Remove unsupported RAM Fuser life test error during Boot cycle - Replace the Formatter A Large print Job (>800 pages) or complex graphics can cause the device to quit printing. - Simplify the Print Job, lower DPI etc.,
You need to get a technician in. The code is suggesting the formatter board.
Note that make sure that the technician (or you if you are replacing it) that once you replace the board and turn on the machine, don't do anything for about 10 minutes. No printing, nothing. Take out the network/usb cord out to prevent anyone from printing. The reason is that the NVRAM (memory) is updating the new board with your information. If anyone prints (whether from a computer or a configuration page) then it will interrupt the update and you will get the same error again.
Not sure about model 49-307, but it's probably the same as modle 49-537...
1) hit *
2) enter old code (which after power-on reset is the factory default of 1234)
3) hit * again
4) enter your new 4 digit code
5) hit * one last time
Your new 4 digit code should now work to arm and disarm it.
If you enter any wrong digits hit the # key to clear the error, and re-enter the code.
