Daikin Altherma hybrid problem (error code 4)
How old is the unit? Has it been running fine for a few years until now? According the the installation model I found (on Google) for model EHYKOMB33AA Error Code 4 (No Flame Signal) Gas tap is closed No or incorrect ignition gap Gas supply pressure is too low or fails Gas valve or ignition unit is NOT powered I don't have one of these units. But on a normal, indoor natural gas furnace at least, this typically means that the flame sensor is dirty or has a poor connection. My furnace does this every few years. I remove the flame sensor (which is essentially a temperature probe that senses the heat of the flame when it ignites) clean it with some light sand paper, and then put it back. Being sure to plug/unplug the wiring harness multiple times to scrape off any oxidation on the contacts. See if you can watch it start up. Does the burner come on for a few seconds and then shutoff? That's a dead ringer for the flame sensor. Or, does the gas not ignite (the igniter will typically glow read hot or spark/click (piezo)? Or is the igniter good, but no gas is coming out?

November 21, 2024My Daikin brc1d52 constantly shows E3 error and shutdown, technician says i have to turn it off completely for 24h, so the auto-test resets, is it true ?
Looking it up the E3 code seems to be high pressure so that wouldn't even make sense if you were leaking refrigerant your outdoor coil Maybe dirty your fan could be dropping out but either way I don't think turning it off for 24 hours is going to make a difference More on reddit.com

August 22, 2023Anyone have any experience with these units? Getting error code E04 on tstat, supposedly it means communication error from outdoor unit. Checked pressures, wiring, low volt, high volt, everything is wired correctly. Any ideas???
I had this issue on a Panasonic. Issue was I didn’t have shielded Tstat wire running from outdoor unit to indoor units. This error could be caused by a multitude of different things. More on reddit.com

r/heatpumps on Reddit: Daikin Altherma hybrid problem (error code 4)
November 21, 2024 -
Based on daikin EHYKOMB33AA instructions, the error code 4 means no gas.
I would have expected that the system would keep working on electricity only, but it completely stopped working. Is this normal or just my settings are not correct? Do we have technicians on this thread?

So che è di 3 mesi fa, ma rispondo ugualmente. Le ibride (Daikin) NON possono riscaldare l'acqua calda sanitaria (ACS) con la pompa di calore a meno di non avere anche il serbatoio d'acqua. Anche d'estate, coi pannelli fotovoltaici a pieno ritmo consumo gas per ACS. In più se accade un errore alla pompa di calore, la caldaia continuerà a funzionare in solo Gas. Viceversa si blocca tutto. Dogma di fede..
