GW712 - error 49

Hi.

In reference to your suggested fix for error 49 - replace blown FET (Q842, Q822).. What are the substitute parts used as I cannot locate the orginal part (D2NC60/WKF317)

I have successfully used a D1NA60 FET from an earlier version (phase 5) controller to replce the D2NC60. It is a lower rated component but it works. It was necessary to replace the cold solenoid valve (had gone low in resistance to 15 ohms) and the on-board wired fuse as well but all works OK.
A higher rated FET which could be substituted is ST D5NM60.

How To Fix The HP Printer Error 49?


The HP printer 49 error is a result of an internal communication issue where the firm has led to a critical error and the formatter processor has simply aborted its operation. The error also has letters defined as XXXX which refers to the issue of this fault. HP records these messages so that if they have started recognizing a high level of error with the same fault address they can easily focus on making various changes with the firmware or other such parts to help prevent the error from executing on repeated basis. According to HP technical support experts, it is said that the error 49 error is a serious cause of a bad printing command, corrupted data, various invalid operations, firmware, formatter, or even it is possible due to EIO card or memory accessories.


Steps to fix the HP Printer error 49

Step1: Power-Off Phase

    ·Power off the device and then carefully disconnect all the communication cables; Network, USB, or Parallel cable.
    ·Wait at-least for 30 seconds and then turn the device back on. If the error still exists then it is a possible device error. If the error does not go away then it is a symbol of Communication Between the Computer and Network Step2: Managing the printer
      ·Unplug the printer and then carefully remove all the accessories such as EIO cards, memory, extra trays, duplexer (if removable), and envelope feeder.
      ·If the error does not exists after you have powered on the printer, start reinstalling the parts one at a time, by powering off before you go ahead with the installation phase of each part till you find the error cause. Next, the firmware needs to be updated to fix this type of issue. Step3: Further method
        ·If the 49 error is present in the printer after removing possible causes then try a cold reset or NVRAM initialization method first. A cold reset process will further reset every minor stored memory settings such as control panel settings or internal and external jet direct settings. NVRAM is more elusive as well as clears out all the internal memory such as error logs and other possible counters.
        ·If this 49 error continues to exists, it is advised by HP tech support experts to replace the firmware DIMM, if there is one.

I have just fixed one of these. The problem was C104 inside the metal shielded section of the PSU. It's a 2.2uF 50V capacitor. Sony used an 85degC version rather than a 105degC (which I've used). Fortunately, no other components were damaged.

FET Error


FET error is caused by a short in the driver transistor on the motor controller. Unfortunately, the fix for this is to replace the motor controller.

My Hifonics BX1500d is still going in protection mode... can that be fixed? greets Gerben


sorry, i am in the US. I couldnt begin to tell you where to get your amplifier repaired.

Try contacting HiFonics at www.maxxsonics.com


There are 3 possible conditions a HiFonics amplifier will go into protection -

Ground Loop - Blown or damaged speaker causing damaged Output FET.

Power Supply Failure - Blown Capacitors, Damaged FETs, Faulty Relays.

Thermal Shutdown - Excess Heat.

Mono channel amplifiers are the simplest to work on - and I would Estimate a repair cost of $75USD if it is a simple FET replacement.

Look at one hour of labor plus parts.

Hope this helped.

Washing Machine won't work


Sounds like error 49.
A water solenoid. I bought mine for $40 on ebay. FP didn't want to help. I still had the same problem after so I did a bit of chasing. I wasn't going to pay $350 for a controller, they must cost about $30 to make!

If you look closely at the solenoids you may see a bulge or burning.



I replaced the solenoid but still had binary 49 LED code. I chased the circuit through the Motor Controller (brown one in Australia) GW712.

It was a couple of FETS or Qs in a H drive. The get fed their +v from the main power rectifier. There is a funny looking round component called F^ which is a quick blow 1.6 A fuse. Because my solenoid had a shorted turn on it (bubling to outside packaging) it had blown this.

I didn't have one instock so I substituted an ordinary glass 2AG 2.0amp fast blow. You need to remove the old fuse and solder 2 wires into the holes left these are inturn soldered to the fuse ends. I used hot glue to hold the fuse clear of any other components.

You can get slow blow fuses almost anywhere. In my experience ordinary fuses are the same they always fail after the components are lost anyhow!

If you are desperately dirty you could just jump the 2 holes with tinned copper but this could represent a fire hazard if a solenoid goes again.

We amke microcontrollers. It is a simple fix and saved me $350. A fuse is 10c or maybe $1 if you buy them one at a time. Make sure you test the plugs before you start up. My GW712 read:

1. Each motor winding ~ 35 ohms to any other
2. The lid solenoid ~ 70 ohms
3. Each water solenoid ~ 60 ohms
4.The thermistor ~ 10K ohms


# When this fault exists you can empty the water by removing the tube to the Pressure Xducer and using a tube from your mouth to blow into it HARD!!! The pump will start and pump it out for you.

To calculate the error code (for what use that is when you can find out)
