The water play area at Millbrook Park is being closed again.
The engineers from the company that installed the tanks and pumps have been called back to Jersey because of the ongoing issues.
They'll spend two days in the island to fix the faults.
The area will be shut on Wednesday 24 August and Thursday 25 August.
It first opened on Friday 17 June when temperatures reached 33.2°C, but was closed a day later because of issues with the water quality.
After reopening four days later, it was closed for a few hours on Tuesday 12 July to repair a pump.
It then didn't open on time on Saturday 16 July because of 'technical problems.'
It closed again earlier this month for planned maintenance work.
