    What does 'WARN: CASING TEMP HIGH' mean on my EBARA Water Pump?
    • M
      Maria GrimesAug 31, 2025
      If your EBARA Water Pump displays 'WARN: CASING TEMP HIGH', it could be due to a rise in pump back pressure, an increase in the gas load, accumulation of by-product, or reduced cooling water flow. Check the exhaust pipe, reduce the inflow gas amount, replace or overhaul the pump, or increase cooling water flow.

    Why does nothing appear on the LCD of my EBARA EV-S20P Water Pump?
    • O
      othomasAug 29, 2025
      If the LCD on your EBARA Water Pump shows nothing, it could be due to several reasons. First, check the power supply to ensure the pump is receiving power. Next, verify that the connector is properly connected. Also, make sure the CP is turned ON. Check the LCD’s connector to ensure that it is connected. If none of these steps resolve the issue, the instrument may have failed and need replacement.

    What causes 'ALARM: CASING TEMP H.HIGH' on my EBARA EV-S20P Water Pump?
    • T
      tdavidAug 28, 2025
      If your EBARA Water Pump displays 'ALARM: CASING TEMP H.HIGH', the pump back pressure may be rising, there may be an increase in the gas load, cooling water flow may be reduced, or there may be an accumulation of by-products. Check the exhaust pipe, reduce the inflow gas amount, cool the pump thoroughly and reset it, or replace or overhaul the pump.

    What does 'WARN: WATER FLOW LOW' mean on my EBARA Water Pump and how do I fix it?
    • R
      Ryan TaylorAug 27, 2025
      If the EBARA Water Pump displays 'WARN: WATER FLOW LOW', it could be due to several reasons: * Coupler is disconnected, so connect it. * Pressure is insufficient, so apply sufficient pressure. * Root valve is closed, so open the valve. * Water pipe is clogged, so clean or replace the piping. * Tube fittings are loosened, so re-tighten them. * Instrument failure, so replace the instrument. * Outlet & inlet pipes are reversed, so connect the pipes correctly.

    Why is my EBARA EV-S20P making abnormal noises and vibrating excessively?
    • L
      lorihansenAug 27, 2025
      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.

    What to do if EBARA EV-S20P shows ALARM: WATER FLOW LOW?
    • D
      Darlene SteeleAug 26, 2025
      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 the circuit protector activated on my EBARA EV-S20P?
    • M
      Michael RiveraAug 25, 2025
      If the circuit protector is activated on your EBARA Water Pump, it could be due to incorrect wiring or a short circuit. Check the wiring first. If that's not the problem, the pump may have a short circuit, requiring replacement or overhaul.
