Bosh sgs5362gb skips time

Hi

We have the Bosh sgs5362gb the problem we been noticing for a few months that cleans were not always clean.

What we noticed recently was that on the quick wash the dishwasher will start displaying 45 min remaining to complete, we go back in 30min. the display will show 16 min remaining but after a minute the display will show that only 2 minutes are left, so skipped from 16 to 2, after the 2 min it will show as 0 remaining, when we open it the cycle will be finish and water drained but some dishes might not be clean properly. It might been happening for a while but not noticing.

Also I checked the drain inside the dishwasher that will see is dirty the water and filter, I thought that the water at least should be clean.

I just remember now that I while back was the opposite and time remaining will go up by about 15 minutes (we haven’t seen it for a while but might had been in longer cycles but not sure)

Our dishwasher was affected by a recalls a while back so some part was replace, not sure if the issue is since them or was happening before.

Any idea what it could be?

Thanks
