Non-Functioning or Poorly Functioning SBE 5M
Perform the inspection procedures listed above in Yearly Maintenance for SBE 5M. If you do not discover the problem
there, proceed as follows.
1. Unscrew the pump head from the housing.
2. Pull out the end cap from the housing.
3. Pull out the electronics from the housing. Note that the electronics are wired to the bulkhead connector inside the
housing.
4. Verify that the magnet can spin freely and is not broken or damaged.
5. Look for other signs of damage.
6. Apply a light coat of o-ring lubricant (Parker Super O Lube) to the o-ring and mating surfaces. Reinstall the
electronics in the housing. Reinstall the end cap in the housing, carefully aligning the end cap with the housing and
pushing hard on the end cap to seat the first o-ring in the housing (only 1 o-ring should now be visible).
CAUTION: If you are not careful, you may pinch the o-ring, which may allow water to enter the housing,
damaging the electronics.
7. Reinstall the pump head on the end cap.
