NOTE
All complaints come from end users, so, we use the same words as end users used to describe the problem when they are facing, so that technicians could find out solution easily via complaint name.
In order to let technicians find out solution in a less range to focus on problem solving, we divide all complaints into 7 groups, based on the property of complaints and function attributes,
Below is the relationship diagram for complaint, and illustrations for each group and each complaint.
NOT WORKING
This machine is just used for clothes ironing, with co-working of heating system and water circuit system.
Here, when we talk about "not-working", it means that:
1. The iron could not deliver steam.
2. The soleplate could not heat.
3. There are warnings on display.
4. There is nothing shown on display when connecting to power source.
There will be two possible situations- with and without warnings on display.
• Refill indicator could not be removed after refilling.
• Descaling indicator could not be removed
• The icons of power and refill indicator flash alternately
• The icons of power and descaling indicator flash alternately
• The icons of refill and descaling indicator flash alternately
• The icons of power and refill and descaling flash 5 times before automatic power-of
• The icon of steam rate flashes over 3 minutes
• Nothing shown on display
• No steam delivered
• The temperature indicator light is not on
QUALITY OF STEAM
The machine could deliver steam and heat the soleplate, but the quality of the steam or soleplate temperature is not good, mainly performs as:
1. The steam amount
2. The water drips
• The steam amount is less or more than defined rate
• Water drips from soleplate
ABNORMAL NOISE
The machine mainly relies on the pumping system to pump water into the steam generator and heat the boiler to produce steam.Thus, it is normal that you can hear the pumping sound when switch-on the appliance
However, if you hear some abnormal noise, it is very likely there are problems with the components, or there is movenents of loose components inside or drip sound during working, we can judge this is abnormal noise.
Below is abnormal noise list based on components.
• Electric noise
• Air pumping noise
• Abnormal noise of the loosen components inside when appliance working
LEAKS
In water circuit system, when the leaking amount is large, water leaks out completely or partially, there will be no steam delivered, or the steam rate is much less than defned.
Therefore, here the cases we mainly consider are the leaking amount of water much lower that could not be perceived to leak when ironing. But after several uses, water fows out from the machine.
Or when steam ironing, the steam comes out not only from the soleplate, but also the machine body or the iron body.
• Water leaks from machine bottom
• Steam leaks from steam tubes or release automatically
RELIABILITY
The ability of product to complete specifed functions under specifed conditions and within a specifed time is called reliability.All components in this machine has its reliability defnition and requirements.
However, here the reliability we talk about is related to the components that are opened or operated frequently during users' dailyusage, included as below:
1. Temperature dial knob
2. Water tank
3. Button on display
4. Iron lock
5. Steam trigger
• No click sound when turn the temperature dial
• The water tank could not fx well
• Button on display doesn't work time to time
• The iron lock could not fx the iron on the base
• The temperature indicator on iron doesn't work
• The shot of steam function doesn't work
• Some or all icons doesn't illuminate while working
• Steam trigger could not be pressed
• Iron base is deformed or soleplate is loosened
• No dirty water is ejected after descaling
SAFETY
This machine is a steam ironer, including heating system and water circuit system.
All these systems are generated by electrical power to heat and move. Thus, the considered safety problems normally are electrical shock and scald.
Below is safety issues list based on components.
• Electrical shock from machine body
• Heat injury from machine body
APPEARANCE
Appearance issues maily mean scratches, dents, crack on surface of machine body or its accessories.
• Water tank and its handle
• Insulation base, unit base cover and control board assembly
• Base decoration ring, left & right piece and Unit base body
• Power cord and cord bushing
• Iron handle cover, support seat and dial knob
• Iron body, decoration piece, cord bushing, iron lock knob and its baffle
• Soleplate and iron base
• Connection wire assembly
