Chihiros heater pro EE3 error- Heater element not functioning.

[Hatz]

G'day Guys,

I just had your Chihiros inline heater pro sent to me in the mail and was really excited to get it all in and set up.

Unfortunately the heating element doesn't seem to want to start to function and shows "000W" consistently, even with higher set base temps than water temps.
After a couple minutes of being powered on it shows device malfunction in the app and error code EE3 on the device screen.

I am in Australia- using 240V and 50Hz. Below are my device details.

Incase of a system bug, at the time of this post I conducted a reset on the device and set the device to 800w.

Can you please advise me if I need to organise a new device?

Cheers,
H

What plug you use, AU plug?
You can ask the seller for after-sale service.

Could we please get an explanation as to why the EE3 Error message is appearing and what can be done to rectify this apart from simply going back to the retailer? Can this be fixed? It sounds from your reply - that this is not fixable? Is that true?

A part inside got short circuit, cannot be fixed.

This error occurs due to poor engineering design of this heater. Chihiros replaced the thermostat manufacturer and redesigned the main board in later revisions. This means the thermostat ksd301-g 250v 16a 160C contact has burned out. The thermostat ksd301-g 250v 16a 160C is of poor quality. I would replace it with a ceramic one, but not the cheap Chinese brand that's installed as standard. I had 3 of these heaters fail, even to the point of melting the case and charring the inside of the glass-filled plastic chassis.
I got them replaced under warranty. But I'm currently rebuilding all three new heaters. All the versions have errors:
1. The heatsink is poorly screwed to the JST16A 800bw Triac; it's loose and the pressure is poor, which could cause the heater to fail. I'll be replacing it with a higher-quality BTA16-800BWRG.
2. The polarity of the capacitor numbered EC4 is reversed, which could cause failure or even an explosion.
3. There are some poor soldering spots. I'll be re-soldering everything.
4. I'm replacing the KSD301-G 250V 16A 160C thermostat with a high-quality ceramic one rated for slightly less than 145C. I also plan to install a 250V 16A 170C thermal fuse on the heating tube, on the neutral wire. The heater is easy to open: just pry the rubber inserts out of the housing and unscrew the screws.
The thermostat also needs to be coated with thermal paste for better temperature control.

Don't lie! Everything can be fixed perfectly and easily. You should be ashamed of such poor quality assembly and design. My house almost burned down because of your heater errors. Strengthen your final quality control, don't skimp on electronic components, and don't put junk in your heaters.

Replace the thermostat with a high-quality, brand-name one. I would choose a thermostat KSD301-G 250V 16A 145C with a lower operating temperature—145°C. The stock thermostat is a cheap, no-name Chinese knockoff. Also, clean the terminal contacts if they're blackened, and bend the terminals for better, tighter contact.

You can ask after-sale service to replace.

You don't read well and don't understand. My old heaters were replaced under warranty with newer versions. The newer versions also have assembly issues and component quality issues. I had to redo three heaters after your clumsy assembly.
Strengthen your final quality control, your external heaters are a fire hazard.
