I don't have a subscription so can't see the full article, but Rail are reporting that Lumo's 222s are in worse condition than expected on transfer

It doesn’t give much detail on the actual issues, but does mention the toilets issue (specifically the 0611 Euston -> Stirling on 7 Aug which had 0 of 5 toilets working and made national news because of it).
They also comment that these issues have arisen throughout the trains so far short time with Lumo, and that none of these issues were present at the time of introduction, with an Alstom spokesperson saying:
“Alstom has been working with Lumo to address a number of unprecedented faults on the operator's West Coast fleet, including replacing defective components, carrying out door repairs, investigating and stripping down the affected waste system, and completing tanking and checks to return toilets to service.
We recognise that this falls short of the standard customers should expect, particularly on long-distance services. Lumo and Alstom are reviewing the entire fleet position to reduce the risk of repeat failures, improve overnight servicing checks, and ensure toilet availability is restored and maintained wherever possible.”
They also mention that now all 5 units are in, they hope to send a unit at a time to Central Rivers for a deeper assessment and fix-up than what can be achieved at the moment.
One last thing they add on the end is that the unit that is stabled at Ferme Park overnight cannot have the usual maintenance like toilets getting drained, however they don’t actually say whether that’ll be investigated and fixed if possible, they kind of just state it as something to note.
This is what I think is said in the article, anyone else is free to have their take on it if they can access it of course though.
