Coroner's faulter code ee final guide! 5-step screening + maintenance course + full disclosure of techniques
A lot of sisters have been asking me in private lately what happens when the coroner suddenly jumps out of ee's fault code! As a domestic electric maintenance operator and an old user of the disinfectant cabinet for three years, today's hand is teaching you how to solve this bald ee failure quickly! We've got super-operational maintenance skills to save your disinfectant cabinet
I. What does the ee fail code mean
The meaning of this ee code for pre-cooking: an anomaly (87%) representing internal temperature sensors or thermostats in the disinfection cabinet may be caused by the ageing of the sensor/line contact/heat control damage. Don't panic in this situation
Ii. Ee fail code 5-step (with graphics)
(figure 1: map of the detoxification cabinet in koron)
One basic check
Plug-in loosening test: unplugging power lines, re-plugging and re-opening (35% success)
Same-type disinfectant cabinet: find a stowage cabinet for normal work with the same employee, and observe whether the same was reported as wrong after electronization (excluding batch problems)
Power adapter detection: measurement of the stability of the output voltage (normally 220 v ± 10%)
Two
Focus area:
1 wall temperature sensor in case (usually in mid-level partition)
2 ntc thermal sensitivity resistance on circuit boards
3 box door seals (aging causes temperature fluctuations)
(figure 2: sensor test map)
Operational steps:
1 spray sensor surfaces with alcohol cotton chips
2. Measurement of sensor's resistive value (normal value of approximately 3. 3 k at 25 °c)
3 check for loose connection (focus on power lines interface)
Three
The temperature control damage was the second largest cause of the ee malfunction (62%)
Method of detection:
1 infrared thermometer to measure surface temperature of thermostats (stabilized at 60-80°c for normal work)
2 touch box temperature (normal sterilisation box temperature should be 65°c)
3 checks whether the thermostat switch is holding down (with light-drive levers available)
Four
(figure 3: areas of focus on circuit boards)
1 to detect the pressure of the feet in 10,000 meters:
- vcc end voltage: +24v
- alm end voltage: 0v (+5v at time of alarm)
- tch end voltage: subject to temperature change
2 check for convulsions (focus on c5, c6 electrolytics)
Three, we're going to use a million-dollar meter to break the grid
Five
Replacement programme:
- sensor replacement price: usd 45-85 (recommended to replace plant)
- temperator replacement price: 78-128 inclusive of installation costs
- maintenance of circuit boards: $150-300 (depending on the extent of damage)
Treatment during warranty period:
Contact official guest service 400-820-7665 and provide purchase vouchers for free maintenance (referral testing)
️ iii. Guidelines for the maintenance of pits
Do not self-destruct high pressure components (possibly electrocution)
Avoid the use of poor-quality thermostats (prone to secondary failure)
We have to do more than three sterilization tests after maintenance
It is proposed to purchase extension services (about $298 over three years)
Iv. Routine maintenance techniques (super practical
1 monthly cleaning calendar:
- 75 per cent of the weekly alcohol scrubbing buttons (monthly food-grade cleaning + hot water wipes)
- monthly clean-up of heat vents (cleaning of dust with soft hair)
- quarterly inspection of seals (over 3 mm old to be replaced)
2 use taboos:
It's forbidden to store metal dishes
Avoiding three or more successive full-load operations
It'll take 30 minutes to open the door after the sterilisation
Energy efficiency techniques:
- it's suggested to use "quick disinfection" in summer
- keep the utensils above 1 cm (heat efficiency improvement)
- at least once a month, at least once in depth (with 84 disinfectant + 1:100 water sprayed)
V. Guidance on selected mine avoidance
When comparing parameters, focus is placed on:
Temperature control accuracy (in ±1 °c)
Sterilization (recommended uv+ infrared compound disinfection)
Materials (316 l for stainless steel)
Safety protection (the door lock is subject to error-proof design)
