12. Maintenance Guide 
12-1.Common washing problems 
Many washing problems involve poor soil&stain removal, residues of lint and scum, and fabric 
damage. For satisfactory washing results, follow these instructions.
   
 
WASH PROBLEM 
Problems Possible 
causes 
Solution& Preventive Measures 
Poor soil removal 
● Not enough detergent 
● Wash water temperature 
too low 
● Overloading the washer 
● Incorrect wash cycle 
● Incorrect sorting 
● Do not pretreat stain 
● Use correct amount of Detergent for load size, amount 
of soil and water Hardness. 
● Use WARM or HOT water for normal soil. Different 
Water Temperature may be required according to Soil 
type. 
● Reduce load size 
● Wash with POWER cycle for heavy soiled laundry 
● Separate heavily soiled items from lightly soiled ones. 
Blue, Gray or Brown 
stains 
●Undiluted fabric softener 
dispensed directly onto 
fabric  
● Rub the stain with bar soap. Wash. 
● Do not overfill fabric softener dispenser and do not pour 
liquid fabric directly onto fabric.
 
Black or gray marks 
on clothes 
● A buildup caused by the 
interaction of fabric 
softener and Detergent 
can flake off and mark 
clothes. 
● Not enough detergent 
● Use correct amount of detergent for load size, amount of 
soil and water hardness. 
Yellow or brown rust 
stains 
● Iron or manganese in 
water supply, water pipes 
● Not enough detergent 
●To restore discolored load of whites, use rust remover 
safe for fabric 
● Install nonprecipitating water softener or an iron filter in 
your water supply system for an ongoing problem 
● Before washing, run water for a few minutes to clear 
lines. 
Lint  
● Incorrect sorting 
● Tissues left in pocket   
● overloading the washer 
● Wash lint givers eg towels, flannelette sheets, separately 
from lint collectors eg synthetic fabrics。 
● Remove tissues in pockets before wash. See attentions 
for sorting and caring before loading. 
● Do not overload the washer 
Residue or detergent 
● Overloading the washer 
●Undissolved detergent   
● Use too much Detergent 
● Do not overload the washer。 
● Some Detergents need to be pre-dissolved, check the 
Detergent instructions. Try pre-dissolving the 
Detergent in warm water.   
● Increase Water Temperature using HOT water safe for 
fabric. 
● Use proper amount of Detergent. 
Holes, tears, or snags 
● Incorrect use of chlorine 
bleach 
● Unfastened zippers, 
hooks, buckles 
● Ribs, tears and broken 
threads 
● Never pour chlorine bleach directly on fabric。 
● Fasten zippers, hooks, and buckles。 
● Overloading the washer 
● Degradation of fabric 
● Remove objects in pockets。 
● Do not overload the washer.

12-2. How to diagnose and maintain according to symptoms 
1)  Power Failure 
Where, what and how 
Check results 
Possible 
reasons 
Solution measures 
Power   
 
Yes 
 
Electric 
problems 
 
1. Check if the socket is in poor 
contact.  
Replace plugs 
Normal  
None 
 
2. measure voltage 
0V Power 
supply 
Contact Power Supply Bureau
 
<1Ω 
 
None  
 
 
Washer harness 
1. Measure power cord resistance with 
plug short-circuit   
Infinite  
Power  cord 
cracks 
Replace power cord 
2. Check if all the connectors are 
connected properly. 
Separation of M and 
F connectors 
Poor contact
Connect again 
3. Check all wire resistance Infinite 
Harness 
cracks 
Replace harness 
<0.5Ω None 
 
>1Ω 
Poor contact
Replace power cord 
10-14V None 
 
Replace 
transformer 
Electrical appliance
0V 
Coil cracks 
Replace filter 
1.check if the fuse is damaged Yes 
Bad 
fuse 
Replace 
filter 
PC board 
 
 
 
Replace PC board if all 
appliances are not damaged. 
 
It must be that PC board damage if 
problems are not mentioned above. 
15% higher than 
standard voltage.

2)  Display problem 
Where, what and how 
Check results 
Possible reasons 
Solution measures 
Main voltage 
1. measure main voltage 
 
 
Less than 85% of normal 
voltage 
 
Low voltage 
Because of low voltage 
supply. Please use 
transformer if voltage is 
keeping low.   
2. measure external insert 
row voltage if main 
voltage is normal. 
Less than 85% of normal 
voltage 
Wire is too small or there 
are too many 
connections on insert 
row. 
Use transformer 
PC board 
1.  LED damage 
 
2.  LED drive circuit 
damage 
3.  Chips damage 
 
PC board damage 
Replace PC board 
 
 
3)  Restart during working 
Where, what and how 
Check results 
Possible reasons 
Solution measures 
Main voltage 
1.  measure plug voltage 
during working 
 
Less than 80% of normal 
voltage 
 
Main voltage is too low or 
wire size is too small. 
Because of low voltage 
supply and please use 
suitable wire. 
2. restart fault repeats 
during special periods 
 
Temporary voltage surge 
Because of environmental 
condition(high-frequenc
y voltage around) 
3. check if there is voltage 
change.(such as flashing 
lights) 
 
 
Because of power supply 
environment 
PC board 
 
 
Replace PC board 
1. It must be PC board 
fault if there is no 
main voltage fault.
