Afternoon, been struggling with my sprayer over the last year or so. Every so often it can lose pressure. The flow rate says it’s right amount. But no pressure. If you take it back to manual you can get 1 bar of pressure when you Rev the nuts of it and open it right up, also says its doing about 200 litres a minute which it isn’t. Changed the flow sensor and pressure sensor. No leaks anywhere I can find. Could be the pump? But they usually leak?
