SIGURO is a "corporate brand" of ALZA, but based on the ETA brand, this eco model GREEN in action for 9400 CZK (December 2023, regular price 11000 CZK) fully corresponds to the highest model of the dishwasher ETA for 14000 CZK (specifically ETA 239490001B, programs and instructions are almost the same, including the error in the salt and polish settings). But ETA has an extra tablet program, and because it's integrated it projects the time on the floor, otherwise it's the same (and it still only reads 40 dB, maybe it has a slightly more muted door). /// This is our 4th dishwasher, I have experience and I am a technician who enjoys measuring. Our previous dishwasher was an AEG FAVORIT SILENCE PLUS, we had it from about 5 years to 13 years and it had to be repaired with 8 defects (230V/10 relay in the door, tachogenerator in the motor, hoses downstairs broke, two right away, the drain pump went last year and still stopped working and letting water Aquastop. Compared to the AEG (new still around 2009 15-16 thousand), THIS SIGURO GREEN WASHER is the BEST ON THE MARKET, it is significantly better and higher class. No need to worry and buy "proven" German brands. Bosch isn't what he used to be. Big praise to Alza. //// I had no idea that if the dishwasher is not sold, there is a difference between the best A or B and C, D, E class only in software! how much water it heats and how much it eats. If you want class B, it will heat the minimum amount of water and only 2 times and it will still be 50°C and 40°C. These are the laws of physics. A better dishwasher is often no better (yes Miele probably is, but the price. ), but simply has the cycles and water temperature set differently. //// If the manufacturers wanted to, a regular dishwasher for 7500 crowns would be class B just by setting the temperature and amount of water differently. So again, a scam, you are actually just buying a more refined "firmware". If someone could "reflash" it, they could easily turn any C or D dishwasher into a B class dishwasher. The only sensible thing I can imagine is a heat reservoir, so that the discharged hot water heats up the incoming water (better dishwashers do have this. //// Otherwise, the WASH WATER consumption is always measured on ECO = lower temperatures and therefore long washing times. Other common programs also tend to have higher consumption - perhaps very similar to the "worse" dishwashers (typically up to around 1 kWh, pot pans up to 1.4 or 1.5 kWh). CONCLUSIONS: You can't go wrong with Siguro GREEN!
