What country are you in zxen. I have different advice depending on the country.
Anyway I never heard of "ER02". There's 3 heater related errors I think. They are something like:
Heater error
error stopped - temp sensor
error stopped - bed temp sensor
They are very different errors and caused by different things but I'm going to guess the "bed" one since you took that apart. Still if you are getting one of the other 2 then you took the wrong thing apart - sorry.
Building marlin is quite difficult. I used to have instructions but they no longer work so I don't know how to build it anymore. Besides if the problem is in the bed itself, rebuilding marlin wont' help.
The temp sensor in the bed is a PT100 part. Unlike other types of temp sensors, all PT100 parts have an identical curve so you can get any brand, any manufacturer and they all have the same temp curve (resistance to temp curve). So measure the resistance - it should be about 108 ohms at room temp. If it's within 10 ohms of that then it's probably working. Measure at several places to figure out where it is failing.
My bed had a problem early on - within the first 100 prints. I did what you did - removed the terminal block and resoldered all 4 connections. It has been fine for years since then and never had to do anything since.

These replacement heater beds come with the wire block attached for US$65. If you add waiting time to that as an inconvenience of $100 per day, it will cost you up to 40 days ($4000).
If you own an Ultimaker, its likely you'll need to replace these quite often.
