What to do if EBARA EV-S20P shows ALARM: WATER FLOW LOW?
If the EBARA Water Pump displays 'ALARM: WATER FLOW LOW', several issues could be the cause. It might be that the coupler is disconnected, the pressure isn't sufficient, the root valve is closed, the water pipe is clogged, tube fittings are loosened, there's an instrument failure, or the outlet and inlet pipes are reversed. To resolve this: * Connect the coupler if disconnected. * Apply sufficient pressure. * Open the valve if it's closed. * Clean or replace the piping if clogged. * Re-tighten any loose tube fittings. * Replace the instrument if there is an instrument failure. * Connect pipes correctly if they are reversed.
Why is my EBARA EV-S20P making abnormal noises and vibrating excessively?
If your EBARA Water Pump is experiencing abnormal noise and excessive vibration, here are a few possible causes: * The adjustment feet may not be applied, so use them. * Some object might be making contact with the outer cover, so remove it. * The fastening screws of the outer cover may have worked themselves loose, so tighten them. * Parts of the pump may be damaged, requiring you to replace or overhaul the pump.
