Read the CURRENT (A) drawn by the suction motor, note the value then proceed with the next test.
23
Replace the foam retardant sponge H and cap G in position (closing the intake).
24
Press the button M again to start the suction motor.
25
If the draw value read is the same in both tests (with the cap G raised and with the cap G in position) and is
within the values in the following table, proceed to check current draw with the hose E capped.
26
Press the same button M to start the suction motor again.
27
If the draw value read is included between the two values in the following table, this means that the motor is
still in good condition. Remove the clamp, lower the detergent and dirty water tanks, mount the suction hose
E and reset AutoPowerOFF to ON.
28
If the values do not correspond to those specified:
28a
If the draw value in the first test is within the values in the table, but is very different from the value of the
second test (lower), check the piping in the tank and the hose E, making sure they are not obstructed or
crushed.
28b
If the draw of the suction motor with the hose E capped is higher than the value given in the table and
similar to the suction values without load (first two rows of the table), check there is no air entering through
the hoses or gaskets.
28c
Check there is a voltage of about 10 V DC at the end of the control wires A3.
28d
If all of the above points are OK, replace the suction motor with a new one.
Draw A (amps) Min Max
Without load (with cap G raised) 20 A 22 A
Without load (with cap G in position and hose E detached) 19.5 A 22 A
With full load (with cap G in position and hose E capped) 18 A 20 A
