The digital monitor is an important part of exercising on your Water rower.

Most Water rowing machine console problems are the result of low batteries.

Water Rower Monitor Not Working – Troubleshooting Guides

The first to troubleshoot your Water rower is to replace the display monitor batteries to see if it fixes the issue

1. Replace the monitor batteries

A Water rowing machine monitor requires four AA batteries. Alkaline batteries are also recommended to use.

Try not to use old and new batteries together or alkaline, standard, and rechargeable batteries together. 

If the Console has been exposed to cold temperatures, allow it to warm to room temperature before you insert batteries. Otherwise, you may damage the console displays or other electronic components. 

Start off the Water rower battery replacement process by removing the screws fastening the Battery Cover at the rear of the monitor, then remove and discard the old batteries.

Replace all of the batteries, and make sure they are facing the right direction and that the connections are clean, free of damage.

Reattach the battery covers and turn on the Water rowing machine monitor.

2. Reset The Monitor

If your Water rowing machine monitor does not boot up properly, or if the console freezes. A factory reset to the factory default settings might be your solution.

Doing this will erase all custom settings you have made to the console. 

Resetting the console requires you to press the ON button for 2 seconds, the console will be reseted and back to the default settings.

3. Adjust The Monitor Sensor Disk 

If your Water rowing machine S4 monitor is flashing zeros and not counting down, there is one simple check you can do that may solve the problem. 

You basically need to check the position of the Sensor Disk. 

The correct position of the sensor assembly in the top deck. The sensor needs to be moved towards the wiring and lifted up just slightly.

To adjust the Monitor Sensor Disk, you need to locate the black plastic sensor disk located above the clutch.

First check for any damage on the sensor disk ( missing/broken sensor disk teeth). If damaged, the sensor disk needs to be replaced.

With the Top Deck positioned on top of the tank, position your fingers on either side of the round Sensor Disk and lift it up slightly towards the underside of the Top Deck. If the Sensor Disk does allow a small movement upwards this may solve the problem.

This allows the teeth on the top face of the disk to engage and give information to the sensor and monitor.

Be careful not to push the Sensor Disk too close to the Top Deck. You will know it is too high if you hear a squeaking sound as you row.

Row several strokes to ensure the monitor is reading correctly.

If the disk is as close to the Top Deck as possible and the monitor still flashes zeros, then you need to check the sensor wire connections.

4. Check The Wire Connections

You would want to remove the Water rower monitor from the frame and check that the wire that comes from the computer is properly connected to the wire that comes from within the frame.

Using a small Phillips screwdriver, remove the 4 small screws and S4 Monitor board from the backplate housing.

With the main wire now accessible, check this wires connections and pins.

These pins sit inside the plastic casing that connects the wire to the controller or console. You need to make sure none of the pins have been broken or bent. 

If a bent pin is found, carefully bend it back into place.

Identify and check any pinch points the wire may have. Pinch points are any place the wire moves between two parts. 

If this wire is damaged anywhere, you may want to replace it.

If no damage was found, reconnect the wire to the monitor back in, and check if the console works now.
