The trust's acute wards for adults of working age and psychiatric intensive care units, as well as wards for older people with mental health problems, were also dropped from good to requires improvement following an inspection in February.
Inspectors found infection prevention and control measures weren't being met with chipped paint in bedrooms, graffiti on bedroom walls, no running water to the sink in a bedroom, a blocked sink in another bedroom, as well as a blocked toilet in the main bathroom that was overflowing.
Fire risk assessments and care plans weren't up to date, and staff didn't always have the right skills and knowledge to meet people's needs.
Chief executive Dr Sara Munro said: ‘We are naturally disappointed with some of the findings in these reports, particularly where we felt additional context and evidence provided during and after the inspection could have been reflected more in the final assessments. In light of this, we will be asking the CQC to re-inspect all three services as soon as possible.
‘Given the time that has passed since the CQC's assessment, several actions to address areas for improvement have already been completed, including all the environmental issues raised at the time of inspection. We will continue to build on that progress with our staff, patients, carers and partners.'
Actions taken by the trust since the assessment include: strengthening governance arrangements; enhancing safeguarding oversight; improving care planning processes; addressing environmental concerns, and improving compliance with mandatory training requirements.
