TROUBLESHOOTING
Below is a list of frequently encountered operational problems and some guidelines and trouble shooting checks. This
section can only be a guide to solving potential problems with the RO unit and does not contain all possible
malfunctions. The best troubleshooting tool is your knowledge of the RO gained through experience. Situations not
covered in this section may be resolved by contacting the Village Marine Tec
Service Department via phone calls
and e-mail.
1. Check for proper valve configuration. Especially make sure the cleaning valve is in the overboard “Normal”
position. Confirm by checking water is flowing overboard through the brine discharge. Flow should be about a
quart a minute.
2. Always check for loose connections or broken wires when checking electrical parts. Check for good voltage at
the high pressure pump motor; and if it is low then follow back with the voltmeter until the loose connection is
found.
3. Confirm that a free sea water feed is supplied. A) The through-hull is clear of trash or kelp. B) Seacock is open.
C) Sea strainer is clear. D) Boost pump is running. E) 5 micron filter is clean.
4. To flush the unit, the black handled BYPASS VALVE is in cleaning position, but the gray handled CLEANING
VALVE must be in the “Normal” position. During flush, water must be flowing overboard through the brine
discharge.
5. Low production GPH may be caused by cool seawater. Poor salt rejection may be caused by warm and/or salty
seas. Do not interpret environmental factors as equipment problems.
