I start the wash cycle timer reads 1:02 machine runs and timer counts down to 54 mins. then resets to 1:12 mins. which inturn adds approx. 18-20 mins to wash cycle why the reset??

sounds like you have a problem with the main control board. you can order a new one from appliancerepair.com and if it turns out not to be the problem they allow you to return it for a full refund. great company!

The heating element maybe faulty,
or even the thermostat .
If one is not working,
and the temperature does not get to the required temp,
the washer reboots, and tries again,ect

What is the model number?

Hi there.
I have the same problem with my machine. Whatever program I select, the machine runs fine until it reaches 54 mins of the cycle remaining. To overcome the problem just to select a cycle that will not stop mid cycle, select a program which is less than 54 mins. I think the 40 degrees and quick wash select is the one to run with. The cycle is 45 mins, obviously less that 54 mins. The LED timer will display the cycle time. No problems with this cycle whatsoever. Not the total solution, but at least you're able to complete a cycle. After it's completed, I also run the spin program at 1200rpm. I hope this helps.

Make sure there is no water in drum.
Remove and clean pump filter, this is usually located at the bottom front right of washer, behind drop down cover.
Unscrew anti- clockwise to remove and clean.
Good luck.

i have checked all my tech info and error codes only go to f 12!! never had f 17 but based on description sounds like either flow sensor or inlet valve failure will need service tech to sort out but if either of these will not be expensive.

bosch 1200 classixx not working properly. On 12 min spin cycle it starts then after 1 min timer reads 0:01 and it stops. washing cycles run but doesn't seem to be any spin action

I've had this problem, particularly with towels - it's quite annoying & not energy or water efficient at all. According to the manual, the unit has a sensor that senses if there is too much soap & it will continue to wash until the soap is removed. I found that this happened frequently on the "cotton" cycles & max spin. I've tried to make sure I use less soap, but I also use the perm-a-press cycle & the spin 1 down from max. Hope this helps
