My Whirlpool Duet GWH9200L is 11 years old. Until recently, it has run without a problem for 11 years.

Since the F11 code indicates a Serial communication error between the CCU and MCU, I removed and cleaned all of the electrical connections.  "Cleaning" means just spraying with electrical grade contact cleaner. I allowed the contacts to dry and then re-connected.


The whirlpool ran well for another 4 weeks.  Then the same error code has appeared again. It usually appears near the end of the cycle  - often just before the final spin phase.

Knowing that I had recently cleaned the electrical connections, and knowing there is no back up memory battery, I decided not to re-check the contacts, and decided to just pull the plug - and erase the memory for a while. 

About a half hour later I came back to the machine and plugged the power socket in.  The error code was gone. So, I selected the drain/spin cycle   [ which is where it had left off ] and pressed Start.
It ran through the cycle and finished without a problem.

Have you heard of this before?
If this error code were to appear only occasionally, would pulling that power plug out on those occasions, give me time to use this machine a while longer ?
Since the machine is 11 years old, would you advise whether to repair such a machine -- possible CCU or MCU or both --- or wait for a good sale and purchase a newer model?
What is the next step toward diagnosing the problem?

Thanks for your help,


Rodney

Thank you for your post on The Repair Forum today.

With it being 11 years old ,I will say you are VERY lucky it has lasted this long.

If you unplugging the unit and plugging it back in ,gets the unit to run.

I would continue to do that   and save your money for a new one.

But if you want to keep this one and decide to replace parts per Whirlpool replace both CCU and MCU at the same time.
