This message is "Internal Pressure Too Low". Either the internal pressure transducer is off or the idle (unloaded) pressure is too low.

On some machines, there is an idle pressure adjustment on the solenoid on top of the sump tank. Pressure should be 20-25 PSI in Idle (unload) mode

F05 fault after replacing brushes

F05 - NTC failure (SC/OC)
All appliances managed by the electronics measure the temperature using a thermistors. These thermistors changes resistance depending on the temperature. There are two kinds of thermistors, NTC and PTC.
NTC has a negative temperature coefficient which means that with increasing temperature the resistance decreasing (used in washing machine, dishwasher, dryer, refrigerator....etc).
PTC has a positive temperature coefficient which means that with increasing temperature the resistance increasing (used in oven, refrigerator for starting compressor...etc).
If you look in the table below, it is clear that the resistance value of 100 ohm means that is NTC faulty. So, I really do not understand how it is possible that the resistance increases with temperature?

Resistance of NTC depending on temperature
0 °C 35.9 kohm
30 °C 9.8 kohm
40 °C 6.6 kohm
50 °C 4.6 kohm
60 °C 3.2 kohm
70 °C 2.3 kohm
95 °C 1.1 kohm

Neff b6774N0gb/02. Inner glass shattered. replaced. Internal fuse blown. replaced. Now microwave working (heating water) for approx 5 sec, then switching off, beeping and showing E1 fault. Also display...

Usually if this model stops after approx 3 secs it is an invertor or mag fault. Check that the aerial cover is clean Page 3 of the breakdown part position 315. If this is really grubby it would be the cause of the door shattering. The PTC is not used on the microwave function so may be an additional fault. Check also the alignment of the door switches as this can also cause a similar fault. My best guess is if you remove the mag, you'll probably find scorching on it and it (and the invertor) will need replacing.

Hi. I bought a Canon HF100 camcorder. I tried to burn a DVD using a Sony VDR-MC5 via the USB connection. Unfortunately it did not recognise the Canon! If I bought the Canon DM-100 burner I believe it can...

I discovered that the USB connection only works with the Canon DM-100.

I was able to connect the composite cables (red, white, yellow) from the AV out connection of the Canon HF 100. This works fine. It now records on DVD - R; DVD +R:
DVD - RW and DVD + RW.

Hope this helps anyone else with this problem.
