Bloomberg Dishwasher Not Washing? 5 Common Faults, Error Codes and Solutions
Updated: June 28, 2026
In short: In most cases, a Bloomberg dishwasher that leaves dirty dishes suffers from a clogged sprayer or an uncleaned filter. Cleaning the bottom filter once a month and checking the sprayers once every three months solves about 65% of complaints. Code E4 indicates a drainage problem, and E15 is a leak alert. For a repair that requires part replacement - contact Lemarom, Bloomberg's official service provider in Israel.
A Bloomberg dishwasher is a durable and efficient appliance. When it starts to wash poorly, the reason is usually clear and can be solved at home. Sometimes it is a small blockage in the sprayer. Sometimes, however, it is an error code that requires the intervention of a qualified technician. Therefore, this guide will explain exactly what to check first, and when to contactMarom Service.
Why clean the filter first?
The bottom filter of a dishwasher is the most clogged component. Food debris, fabric fibers, and grease build up in it with each wash cycle. As a result, a dishwasher running with a clogged filter forces the pump to work harder, which shortens the life of the appliance.
According to the Bloomberg manufacturer's instructions, the bottom filter should be cleaned at least once a month, and with heavy use - once every two weeks.Source: Official Bloomberg Operating Manual, Routine Maintenance Chapter
How to clean the filter - 5 steps:
About 5 minutes. No tools needed and no need to unplug - the filter is a simple mechanical part.
Clogged sprinkler - do the dishes come out with stains or not clean?
The sprayer rotates and sprays water onto the dishes. Its openings are small, so small food particles can clog them. When this happens, the dishes come out with stains or food particles, even after a full rinse.
From a survey conducted on 38 Electrical Appliances technicians, approximately 62% indicated that a clogged sprayer is the most common cause of dishes coming out dirty from a properly functioning dishwasher.Source: midrag.co.il, Electrical Appliances Technician Survey
Before contacting a technician, you should try:
- Disassemble the upper and lower sprinklers (pull up or rotate - depending on the model).
- Check that all openings are open. The tines of a toothpick clean them easily.
- Rinse under strong running water and check that the water is distributed evenly from all openings.
- Before each operation - make sure that the sprinkler rotates freely and that there is no tool blocking it.
Tip from the field - Micha Levy, Senior Technician at Bloomberg
The lower basket is the most common cause of the lower spray arm being blocked. When a large pot is carelessly placed in the basket, it blocks the spray arm. Check that the spray arm rotates freely before closing the door.
Micha Levy, senior technician at Merom: "A broken or bent upper basket causes dishes to get stuck and prevents uniform water distribution. This is the part we replace the most."
Bloomberg dishwasher not drying - what to check?
Are the dishes coming out of the dishwasher wet? The reason is usually one of three. Before calling a technician, it's worth checking:
| A problem | How to identify | Self-solution |
|---|---|---|
| Rinse aid container empty | Warning light is on on the control panel | Fill the rinse aid container, set to level 3-4 |
| Temperature too low | Wash at 40°C instead of 60°C | Switch to a higher temperature program for the next wash. |
| The heating element is worn out. | The water does not heat up at all. | Requires a qualified technician |
Important to know: Bloomberg uses condensation drying. This means that plastic dishes always end up wetter than glass or stainless steel dishes. Therefore, it's not a malfunction, it's physics.
Open the dishwasher door 10-15 minutes after the program has finished. The hot air escapes, the steam disperses, and the dishes dry faster.
Common error codes: E4, E15, E1
Bloomberg dishwashers are equipped with a diagnostic system that displays error codes when a problem is detected. In addition, the system allows you to detect problems before they become serious. Here are the codes we see most often in service:
| Code | meaning | First solution | Requires a technician? |
|---|---|---|---|
| E4 | Drainage problem - water not coming out | Clean the filter, check that the drain hose is not kinked. | If it returns after cleaning - yes |
| E15 | Leakage protection has been activated. | Tilt the dishwasher forward to empty the tray, dry | If it comes back - check the manual door seal |
| E1 | Heating sensor not responding | Turn off and on again (hard reset) | If it comes back - yes |
| E6 | Door does not close properly | Check that there is no tool interfering with the closing. | If the door is loose - yes |
Code E15 - Do not disconnect from power before turning off!
Before tilting the dishwasher to remove water from the tray, make sure the dishwasher is turned off at the panel. Tilting with the dishwasher on may cause electrical damage.
According to the 60335 standard (Safety of Household Electrical Appliances), any handling of electrical parts of an electrical appliance - including a heating element and a pump - must include complete disconnection from the power supply before operation.Source: Standards Institute of Israel, T.I. 60335-2-5
Original spare parts - why is it important?
A non-genuine part that performs poorly will affect the entire wash cycle. Because Bloomberg manufactures its components to precise engineering tolerances, it is important to use a genuine part when replacing a part.
From Marom you can order original spare parts and accessories for the Blomberg dishwasher - baskets, spray arms, heating element, door seal, and more. All parts come directly from Marom warehouses with a warranty.
What is important to remember?
Cleaning the filter monthly and the sprinklers every three months prevents most problems. Code E4 = Drainage, E15 = Leakage, E1 = Heating. For everything else - contactMarom Bloomberg Service by calling *2620.
Frequently Asked Questions about the Bloomberg Dishwasher
Bloomberg dishwasher model GSN1210 displays E4 and does not drain water - what is the reason?
The E4 code on the GSN1210 indicates a drain problem. First, check that the bottom filter is completely clean and that the drain hose is not kinked. If the problem persists, the drain pump may be clogged and requires inspection by a technician.
Bloomberg dishwasher shows E15 and stops in the middle of a program - what do we do?
E15 is a leak protection code. The float at the bottom of the dishwasher has tripped. Remove the dishwasher from the niche, carefully tilt it forward to empty the tray, dry the inside and re-exit. If E15 returns - check the door seal. A worn seal is a common cause of chronic leaks.
The dishes in the Bloomberg dishwasher come out with white spots - what to do in Holon and the center?
White spots are usually caused by a lack of rinse aid or a low salt level. Fill the rinse aid tank, set the level to 4 and check that the salt tank is full. For Bloomberg technician service in Holon and the center - contact Merom at *2620.
