Water dispenser came down to a trickle and made a lot of noise, I changed the filter but it didnt help and thus the water tank/head assembly needed to be replaced.
Replacing the water Tank/head assembly was an easy task, the hardest part is removing the covers and taking care of not breaking the insulation of the water inlet hose.
For the not-so-experts like me it is also good to rememebr to have a bucket to collect all the water that comes out after the connection to the solenoid valves is removed.
At the end the wife is happy... and that's all that matters
