Getting to Know your Appliance = HOTPOINT WASHING MACHINE




The Model number (which can be found on
the control panel)
The Serial number (which can be found on the
inner door trim)
Model shows the maximum features available on an Aquarius
washing machine.
Cleaning the Dispenser Drawer & Compartments:
It is advisable to clean the dispenser drawer regularly:
Unplug your appliance when cleaning it or carrying out maintenance.
1 Pull the drawer out until it reaches its stop.
2 Press the drawer release latch
down to remove the dispenser
drawer.
4 Relocate the dispenser drawer and push it
firmly back into place.

A B
Clean and dry the
dispenser drawer,
syphons, grate and
fabric conditioner exit
channel (A).
Also, regularly clean the
outlet pipe area (B).
● Do not try to clean any
part of the dispenser
drawer while the machine
is working.
WARNINGS:
● Do not clean any part of the
machine with abrasive cleaners,
scouring agents, acids, any
bleaches or metal polish, as
they may cause damage.
Cleaning the Exterior:
Use a damp cloth or silicon polish to clean the exterior surfaces of the
appliance.
Cleaning the Door Bowl:
Clean the internal surface of the door bowl regularly with a soft cloth.
A build up of soap powder and water hardness residue may result in
water leaking from the door.

General Guidance and service manual can download it here ..

An isolation Transformer should always be used during the
servicing of a receiver whose chassis is not isolated from the AC
power line. Use a transformer of adequate power rating as this
protects the technician from accidents resulting in personal injury
from electrical shocks.
It will also protect the receiver and it's components from being
damaged by accidental shorts of the circuitry that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace it
with the specified.
When replacing a high wattage resistor (Oxide Metal Film Resistor,
over 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to high vacuum and large surface area of picture tube,
extreme care should be used in handling the Picture Tube.
Do not lift the Picture tube by it's Neck.
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source, connect an
electrical jumper across the two AC plug prongs. Place the AC
switch in the on position, connect one lead of ohm-meter to the AC
plug prongs tied together and touch other ohm-meter lead in turn to
each exposed metallic parts such as antenna terminals, phone
jacks, etc.
If the exposed metallic part has a return path to the chassis, the
measured resistance should be between 1MΩ and 5.2MΩ.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before the
receiver is returned to the customer.
Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor
between a known good earth ground (Water Pipe, Conduit, etc.)
and the exposed metallic parts.
Measure the AC voltage across the resistor using AC voltmeter
with 1000 ohms/volt or more sensitivity.
Reverse plug the AC cord into the AC outlet and repeat AC voltage
measurements for each exposed metallic part. Any voltage
measured must not exceed 0.75 volt RMS which is corresponds to
0.5mA.
In case any measurement is out of the limits specified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.
