Symptom/Cause Corrective Measures
Handpiece heats up:
1. Insufficient water to cool
handpiece.
2. Air trapped in the handpiece.
3. Water filter is clogged with
debris.
4. Insert water passageway
clogged.
5. Handpiece cable not
supported during procedure.
6. Worn insert being used.
7. Operatory water supply
temperature is high.
1. Increase the setting on the handpiece lavage control until handpiece runs cool.
2. When the inserts are installed in the handpiece, hold the handpiece in an upright
position until the trapped air is removed and the water flows properly.
3. Replace the water filter.
4. Replace the Cavitron
®
insert and check operation.
5. Loop handpiece cable around arm or support with finger to prevent water
restriction.
6. Replace with a new Cavitron ® insert. Worn inserts require higher power settings
producing more heat.
7. Flush water system before use or use a DualSelect Dispenser as a water source.
Insert vibrates but no water or
insufficient water flows from
the handpiece:
1. Low incoming dental office
water pressure.
2. Water filter clogged.
(Is Water Filter Icon lit?)
3. Handpiece cable water
tubing and wires twisted.
4. Damaged handpiece cable
flow control.
5. Obstruction or mineral
deposits in the water system
in the unit.
6. Water Regulator / Solenoid
out of adjustment.
1. Measure water pressure at dental office. Adjust incoming source water pressure to
specification. Water pressure should be 20-40 psi.
2. Replace the water filter when discolored or restriction occurs.
3. Remove restriction if possible or replace handpiece cable assembly.
4. Replace handpiece cable assembly.
5. a. Remove the insert and turn the handpiece flow control fully open. Observe the
water flow. If the flow is good then the obstruction is in the insert.
b. If the obstruction is not in the insert, then remove the handpiece water line at
solenoid and check the water flow. If flow is good, then the obstruction is in
handpiece tubing.
6. Adjust water regulator pressure according to Dentsply Sirona Preventive SBU –
Product Service SOP PS-00211.
No water flow from handpiece
without insert installed:
1. High dental office water
pressure.
1. Install a water pressure regulator on the main water supply line and reduce the
