5.1 I Cleaner behaviour
The cleaner
becomes stuck on
the steps and other
obstacles for more
than 3 minutes.
• Check the rota onal speed of the wheel, see "3.2 I Checking the rota onal speed of the
wheel".
• Check the behaviour of the back-up valve: remove from the water and check that water is
expelled normally.
• Adjust the thrust jet, see "3.4 I Se ng the thrust jet".
• Remove anything that could hinder the cleaner's movements.
The cleaner moves
very slowly and
operates at a lower
than normal power
level.
• Check the rota onal speed of the wheel, see 3.2 I Checking the rota onal speed of the
wheel".
• Check the in-line lter assembly and clean if necessary, see "4.2 I Cleaning the in-line lter".
• Clean the skimmer basket, the pump basket and the pool lter.
• Check whether the hoses, ngs and ball joints have leaks. This would explain a drop in
water pressure.
The cleaner " ies"
around the pool
and/or does not
make contact with
the pool bo om.
• Check the rota onal speed of the wheel, see "3.2 I Checking the rota onal speed of the
wheel".
• Check the behaviour of the back-up valve: remove from the water and check that water is
expelled normally.
• Check the posi oning of the rear thrust jet, see "3.4 I Se ng the thrust jet".
P280-P380:
• Check that the blue ow restrictor disc is properly installed in the universal ng (UWF) to
reduce the ow rate.
• If the blue restrictor disc is insuffi cient, install the red ow restrictor disc to further reduce
the ow rate.
The robot does not
move backwards.
• Check the behaviour of the back-up valve: remove from the water and check that water is
expelled normally.
• Check the rota onal speed of the wheel, see "3.2 I Checking the rota onal speed of the
wheel".
• Empty the lter bag if full or half-full, see "4.1 I Emptying the lter bag".
• Check that the feed hose is oa ng.
P280-P380:
• Check that the head oat does not contain any water; replace if necessary.
The cleaner only
rotates in one
direc on.
• Adjust the thrust jet, see "3.4 I Se ng the thrust jet".
• Check that the feed hose is oa ng.
The feed hose
becomes tangled.
• Remeasure the hose length and check that it corresponds to that required by the shape of
the pool, see "2.3.1 Measuring and cu ng the lead hose".
• When the cleaner is in opera on, check that the ball joints and hose ngs rotate freely.
• Check that the feed hose is oa ng.
P280-P380:
• When the cleaner is not in opera on, manually move each of the wheels. All wheels must
rotate simultaneously.
P3900 Sport:
• When the cleaner is in opera on, hold it below the surface of the water and check that all 3
wheels rotate simultaneously.
